First Graphene's Strong Advances in VFD Development

Posted By Graphene Council, The Graphene Council, Tuesday, January 28, 2020

First Graphene Limited  is pleased to provide an update of the work conducted in conjunction with 2D Fluidics Pty Ltd on the Vortex Fluidic Device (VFD) at the Company’s facilities at the Graphene Engineering and Innovation Centre (GEIC) in Manchester, UK and Flinders University

Background Summary on Graphene Oxide
Graphene oxide (GO) is the chemically modified derivative of graphene, whereby the basal planes and edges have been functionalised with oxygen containing functional groups such as hydroxyl, epoxy and carboxyl groups. These oxygen functionalities make GO hydrophilic and therefore dispersible, forming homogenous colloidal suspensions in water and most organic solvents. This makes it ideal for use in a range of applications.

To date, the most widely used process for the synthesis of graphene oxide is Hummer’s method. This typically  requires strong acids and oxidants, such as potassium chlorate (KClO3), nitric acid (HNO3), concentrated sulfuric acid (H2SO4) and potassium permanganate (KMnO4). Much work has been done to improve the synthesis methods while maintaining high surface oxidation, however these all required strong acids and oxidants.

Through its subsidiary 2D Fluidics Pty Ltd, FGR is developing a more benign processing route for oxidised graphene. The objective is to provide controlled levels of surface oxygen functionality to give better easier compatibility in aqueous and organic systems. This will not incur the higher oxygen (and other defect) levels which result from Hummer’s method and its subsequent reduction steps. It will also provide the ability to “tune or optimise” the surface oxidation level to suit respective applications.

FGR’s method synthesises GO directly from bulk graphite using aqueous H2O2 as the green oxidant. Different energy sources have been used for the conversion of H2O2 molecules into more active peroxidic species, such as a combination of a pulsed Nd:YAG laser and/or other light sources. The irradiation promotes the dissociation of H2O2 into hydroxyl radicals which then leads to surface oxidation.

The technology has been successfully transferred to the FGR laboratories at the Graphene Engineering and Innovation Centre (GEIC) in Manchester where it has undergone further development and optimisation to identify, understand and resolve future upscaling issues.

XPS analysis showed that the use of pre-treatment step in combination with the near infrared laser gave oxidised graphene sheets with an average surface oxidation of ~30- 35%: this will enhance compatibility with aqueous systems.

Further trials have already demonstrated that the two-step process is reproducible and versatile, with the ability to process different starting materials of graphite. The multi- disciplinary team has identified that control of the feed rate and energy input will allow us to control the surface oxidation, providing a consistent material that can be tailored as required for a range of applications.

Figure 5 shows that increase in surface oxygen content for two starting materials: graphite ore (top) and PureGRAPH® graphene (bottom). As we go through the two-  stage process, in both cases the surface oxygen functionality increases. The end- product has a range of functional groups, including C-O, C=O and COOH.

Next Steps
Operating parameters will now be established to provide yield data for future use in scaling the system for commercial production. It will also commence examining the end applications including, but not limited to the use in electronic devices, testing levels of toxicity for biological applications, for water filtration membranes and incorporation in membranes for studying anti-fouling properties.

Craig McGuckin, Managing Director of FGR, said, “The complementary characterisation techniques used to confirm the synthesis of oxidised graphene gives us confidence we are on the right route towards fabricating a material which is comparable to  the historical GO fabricated using the conventional Hummers method. We are  now  reviewing end applications and thus exploring a number of avenues which include but are not limited to the use in devices, testing levels of toxicity for biological applications, for water filtration membranes and incorporation in membranes for studying anti-fouling properties.”

First Graphene Announces Steel Blue Signs Supply Agreement

Posted By Graphene Council, The Graphene Council, Monday, January 27, 2020

First Graphene is pleased to announce the execution of a supply agreement with Footwear Industries Pty Ltd (trading as “Steel Blue”) for the exclusive supply of PureGRAPH®10 for a twenty-four month term (“Supply Agreement”).

In August 2019, FGR announced that it was able to successfully incorporate PureGRAPH® into a thermoplastic polyurethane (“TPU”). Previously, the ability to successfully disperse graphene into a TPU masterbatch had been a major limitation for the graphene industry. Extensive research by FGR has resulted in a manufacturing method which has overcome this.

While existing TPU’s already possess high abrasion resistance and tensile strength, the incorporation of PureGRAPH® has improved mechanical properties while providing additional benefits in thermal heat transfer and chemical resistance whilst also reducing permeability.

Steel Blue will look to release future work boots with graphene components, including a TPU sole. This will potentially provide new design solutions and improvements in manufacturing processes and the comfort of the boot.

As announced on 15 November 2019, tests on prototype boots were conducted at Viclab Pty Ltd, one of Australia’s leading NATA accredited and independent mechanical testing services. The prototype boots complied with the following test procedures:

Impact resistance
Upper to outsole bond
Interlayer bond strength
Slip resistance on ceramic tile floor with NaLS and on steel floor with glycerine
Sole crack resistance
Tear strength
Abrasion (TPU)
Tensile
Hydrolysis
Fuel oil resistance
Chemical exposure (NaOH)

By including PureGRAPH® additives into the sole, improvements in key properties such as tear strength and abrasion resistance have been measured. Steel Blue have continued to test different applications and processes, with ongoing measuring of outcomes by Viclab Pty Ltd.

Upon successful testing, Steel Blue will look to incorporate PureGRAPH into existing and future models of boots, including the mid-sole and Metguard.

Other Key Terms of Supply Agreement
Pursuant to the Supply Agreement, Steel Blue will exclusively source graphene and any other graphite or graphene products from FGR.

FGR’s supply of its graphene products to Steel Blue will initially be exclusive for application in the production of safety footwear for sale in Australia and New Zealand. Following the initial term, exclusivity will only be available to Steel Blue if Steel Blue has achieved (and continues to maintain) a minimum order quantity. The initial minimum order quantity to be achieved in the second year of the Supply Agreement is two (2) tonnes of PureGRAPH®. Based on the currently agreed ordering schedule, product supply to Steel Blue in year one is anticipated to progress to an annualised basis of one (1) tonne as adoption commences across the Steel Blue footwear range and product lines.

Each party has the right to early termination if there is a material breach of the obligations of the other party. Additionally, Steel Blue has the option to extend the initial 24-month term for an additional 48 months.
 
Craig McGuckin, Managing Director for First Graphene Ltd., said, “The execution of this Supply Agreement represents the first of several anticipated for 2020. We are pleased to have worked with Steel Blue to develop a unique range of safety boots for local and export markets. Graphene is helping our customers to develop new products not previously seen with non-graphene technologies. PureGRAPH® additives are a key enabler in taking elastomers, composites, coatings and concrete materials to a new level and we will continue to seek out further new applications and markets where graphene can add value.”

Garry Johnson, Chief Executive Officer of Steel Blue said “Steel Blue is committed to developing innovative solutions for our customers. We’re excited by the product we have developed with First Graphene. These are two innovative, Western Australian founded companies who are taking new technologies to a world market.’’

Nano-enhanced Boots Successfully Passed Safety Tests

Posted By Graphene Council, The Graphene Council, Monday, October 14, 2019
Updated: Tuesday, October 15, 2019
First Graphene, in collaboration with Steel Blue, has successfully completed safety tests for graphene-enhanced boots which will be used in various industrial sectors. This is the first time that graphene has been used successfully in thermoplastic polyurethane masterbatch, which presents considerable benefits including improved wear and chemical resistance, enhanced heat transfer, and reduced permeability.

This is the first time that graphene has successfully been incorporated into a thermoplastic polyurethane masterbatch and offers considerable advantages, including even greater wear and chemical resistance, better thermal heat transfer and reduced permeability.

Steel Blue is a major global manufacturer of work boots, with a reputation for innovative design to improve comfort, durability and safety. The adoption of graphene to boost these features still further is a continuation of this philosophy, as Chief Executive Officer, Garry Johnson, explains, “Steel Blue is committed to developing innovative solutions for our customers. We’re excited by these recent developments with First Graphene and look forward to delivering these solutions to our market.”

The prototype boots have been manufactured using First Graphene’s PureGRAPH 10 graphene powder. Unlike competing formulations, this is available in high production volumes with non-aggregated, uniform sized graphene nanoplatelets; this ensures that it disperses evenly in thermoplastic polyurethane (TPU) masterbatches.

The prototype boots incorporate PureGRAPH-infused TPU soles and polyurethane foam innersoles and will now undergo extensive laboratory testing, followed by field trials. Craig McGuckin, Managing Director for First Graphene said, “The development work with Steel Blue provides yet another example of how we’re working with customers to commercialise the development of graphene, to transform the properties of materials used in many different applications, from elastomers and composites, to concrete and specialised industrial coatings.”

First Graphene to develop graphene-based energy storage materials for supercapacitors

Posted By Graphene Council, The Graphene Council, Tuesday, September 24, 2019
First Graphene has signed an exclusive worldwide licensing agreement with the University of Manchester to develop graphene-hybrid materials for use in supercapacitors. The licencing agreement is for patented technology for the manufacture of metal oxide decorated graphene materials, using a proprietary electrochemical process.

The graphene-hybrid materials will have the potential to create a new generation of supercapacitors, for use in applications ranging from electric vehicles to elevators and cranes. Supercapacitors offer high power-density energy storage, with the possibility of multiple charge/discharge cycles and short charging times. The market for supercapacitor devices is forecast to grow at 20% per year to approximately USD 2.1 billion by 2022. Growth may, however, be limited by the availability of suitable
materials.

Supercapacitors typically use microporous carbon nanomaterials, which have a gravimetric capacitance between 50 and 150 Farads/g. Research carried out by the University of Manchester shows that high capacitance materials incorporating graphene are capable of reaching up to 500 Farads/g. This will significantly increase the operational performance of supercapacitors in a wide range of applications, as well as increasing the available supply of materials.

Published research1 by Prof. Robert Dryfe and Prof. Ian Kinloch of The University of Manchester reveals how high capacity, microporous materials can be manufactured by the electrochemical processing of graphite raw materials. These use transition metal ions to create metal oxide decorated graphene materials, which have an extremely high gravimetric capacitance, to 500 Farads/g.

Prof. Dryfe has secured funding from the UK EPSRC (Engineering and Physical Sciences Council) for further optimisation of metal oxide/graphene materials. Following successful completion of this study, FGR is planning to build a pilot-scale production unit at its laboratories within the Graphene Engineering and Innovation Centre (GEIC). It is anticipated that this will be the first step in volume production in the UK, to enable the introduction of these materials to supercapacitor device manufacturers.

Andy Goodwin, Chief Technology Officer of First Graphene Ltd says: “This investment is a direct result of our presence at the Graphene Engineering and Innovation Centre. It emphasises the importance of effective external relationships with university research partners. The programme is also aligned with the UK government’s industrial strategy grand challenges and we’ll be pursuing further support for the development of our business within the UK.”

James Baker, Chief Executive of Graphene@Manchester, added: “We are really pleased with this further development of our partnership with First Graphene. The University’s Graphene Engineering Innovation Centre is playing a key role in supporting the acceleration of graphene products and applications through the development of a critical supply chain of material supply and in the development of applications for industry. This latest announcement marks a significant step in our Graphene City developments, which looks to create a unique innovation ecosystem here in the Manchester city-region, the home of graphene.”

First Graphene announce PureGRAPH Incorporated into Steel Blue Safety Boots

Posted By Graphene Council, The Graphene Council, Wednesday, August 28, 2019
First Graphene is pleased to advise that in conjunction with Steel Blue have manufactured prototype sets of safety boots incorporating PureGRAPH®10.

The boots were made last week at Steel Blue’s Malaga WA factory and incorporated PureGRAPH® into the safety capped boot TPU soles and polyurethane foam innersole.

Full boots and the sole samples will be exposed to extensive laboratory tests which are expected to exceed current industry standards for safety footwear. Following laboratory testing it is anticipated extensive field trials, will be conducted, lasting approximately six months.

The incorporation of PureGRAPH® into a thermoplastic polyurethane (TPU) is a major advance for FGR. Previously, the successful dispersion of graphene into a TPU masterbatch has been a major graphene industry issue. Extensive research by FGR has resulted in a manufacturing method which has overcome what was previously seen as a real issue.

While existing TPU’s already possess high abrasion resistance and tensile strength it is anticipated the incorporation of PureGRAPH® will improve mechanical properties while providing additional benefits in thermal heat transfer, chemical resistance and reduced permeability. 

FGR will be conducting extensive laboratory tests on the PureGRAPH® infused TPU and polyurethane foam inner sole in Australia and Manchester. Steel Blue safety boot properties are being enhanced by PureGRAPH® in the Metatarsal Guard (Steel Blue’s Met-Guard), which is specially designed to protect the metatarsal area of the foot that extends from the toes. This is a popular choice for mining workers, factory hands and drillers, who often need the extra protection the Met-Guard affords. 

The incorporation of PureGRAPH® in the Met-Guard will improve both flexibility and strength of the product.

“The development work with Steel Blue provides yet another example of FGR working on real industrial applications” said Craig McGuckin, Managing Director First Graphene Ltd. “Like FGR, Steel Blue is an Australian company and the world leader in its field of safety boots systems. These developments continue to enhance that reputation.”

Garry Johnson, Chief Executive Officer of Steel Blue said “Steel Blue is committed to developing innovative solutions for our customers. We’re excited by these recent developments with FGR and look forward to delivering these solutions to our market.’’

First Graphene Presents at Graphene Automotive 2019 in Detroit

Posted By Graphene Council, The Graphene Council, Thursday, March 7, 2019
First Graphene's  Chief Technology Officer, Dr Andy Goodwin made a presentation at the Graphene Automotive 2019 conference and exhibition in Detroit on 4th and 5th March 2019. Andy was also invited to chair Day 1 of the conference. 

First Graphene provided an update on the measures that have been implemented to ensure the batch to batch quality of PureGRAPH™ products manufactured at Henderson, Western Australia. The Company also presented the latest information on the fundamental properties of PureGRAPH™ products underlining these are righty called graphene materials and also contained an update of progress in key applications. 

The new fundamental data indicates PureGRAPH™ is a low-defect, high aspect ratio graphene product with low metal and silicon contaminations levels. PureGRAPH™ has been shown by microscopy to contain high levels of Few Layer Graphene platelets. Raman analysis indicates the average platelet thickness is < 10 layers. 

One of the impediments to a more rapid commercialisation of graphene has been the inconsistency of quality material available for purchase. While many organisations state they can produce graphene, buyers have had issues with quality. Recognising this issue, FGR has gone to considerable lengths to ensure a high-quality product fit for delivery to industry.

"We continue to implement testing and monitoring tools that ensure the quality of PureGRAPH™ products for our customers” said Craig McGuckin, Managing Director First Graphene Ltd. “we will also continue to publish the more fundamental information on our products as this information becomes available from our ongoing collaborations with leading universities”.

UPDATED ARTICLE: First Graphene's PureGRAPH™ is Demonstrated In A Real-World Application In The Mining Industry

Posted By Terrance Barkan, Wednesday, November 28, 2018
Updated: Friday, October 26, 2018

On 26 October 2018 we reported that the advanced materials company, First Graphene Ltd (“FGR”) (ASX: FGR) released an update on the use of its PureGRAPH™ products in the mining services sector.

FGR has now followed up with a confirmed purchase order for 2,000 kg of their PureGRAPH™ material to be delivered during 2019, for use in the Armour-GRAPH™ product range in a mining equipment application. 

The purchase order for 2,000kg of PureGRAPH™ range products from newGen for delivery during 2019, represents a significant development not only for FGR, but also for the broader graphene market. It demonstrates the initial market appetite for high quality bulk graphene products of the type in which FGR specialises. Up until now the graphene sector has been supplying mostly samples for evaluation. This order represents a step change in the business as it starts to scale up for larger size orders.

Pleasingly, the premium price to be received pursuant to the order debunks the myth that graphene is expensive. The productivity benefits and material performance improvements experienced when PureGRAPHTM is added to materials more than compensate for the cost of the graphene, and it underpins the pricing strategy employed by First Graphene.

As previously reported (see article below) FGR is working closely with newGen Group to provide performance enhancement to their existing products with the addition of PureGRAPH™ graphene products. newGen Group has recently introduced a branded Amour-GRAPH™ product range of wear liners for bucket wheel, pipe spools and conveyor heavy equipment applications.


In a recent development, the Company was pleased to confirm further progress in its R&D collaboration with newGen Group. newGen is supplying a wear lining system for dryer chute applications to a large Australian cement producer in their Perth facility. It is a leading supplier of cement and lime to the Western Australia’s mining, agriculture and construction industries.

Each 50m2 liner will contain 10 to 12kg of PureGRAPH™ and is a further significant step in the adoption of First Graphene products into large industrial applications. PureGRAPH™ has been demonstrated to provide up to 37% improved tensile strength and improve abrasion resistance by 100% to 500% in high performance polyurethanes.

newGen has now issued a purchase order for 2,000kg (2 tonnes) of PureGRAPHTM to be drawn down as it wins tenders during 2019. There is one final regulatory approval required before the first sale is effected, being the registration of graphene by the National Industrial Chemicals Notification and Assessment Scheme (NICNAS) in Australia.

Similarly, the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) needs to be completed for sales in the European Union. These registration processes are currently underway and they are not expected to provide any meaningful delays.

The National Industrial Chemicals Notification and Assessment Scheme (NICNAS) registration process is required for all chemicals used in industry in Australia. Within the European Union REACH registration is required if an organisation plans to sell greater than one tonne of a chemical within the EU or United Kingdom. First Graphene Ltd has already joined the consortium which is registering graphene as a new chemical. The consortium consists of three graphene organisations, one from China, one from Canada and one European producer.

Managing Director, Craig McGuckin, stated: “We said that we were the world’s leading graphene company, and we are now proving it with this sales order – the start of many. We do not believe there is another company which could deliver both the volume and the consistent quality this order requires. We are now entering an exciting growth phase as industries all around the world are starting to look at ways in which they can use graphene to improve their products and lower their operating costs”.

newGen Managing Director, Ben Walker stated: “My Company has had considerable interest generated for our new Armour-GRAPH™ range since we started developing PureGRAPH enhanced products with First Graphene. The graphene enhanced resin was added seamlessly into our mixing procedure. It is not labour intensive or complicated with regard to our standard operating practices.”

ORIGINAL ARTICLE - 26 OCT 2018

FGR is working closely with a number of companies to demonstrate performance enhancement of their products through the addition of its PureGRAPH™ graphene products. In this case, the wear-life of mining equipment can be extended with the inclusion of PureGRAPH™ graphene into protective polymer linings.

The rapid progress made with these polymer linings was enabled by the high consistency of PureGRAPH™ products and the ease of dispersion into the polymer resin. The know-how being acquired is readily transferable to a vast range of other polymer products, in many industries. The suitability of the PureGRAPH™ is particularly pleasing as it confirms this is a commercially superior product.

It is expected that, as manufacturing companies start to witness the improvements that graphene can offer, there will be an acceleration of demand for supplies of PureGRAPH™. First Graphene is well-positioned to satisfy the demand as it enters an exciting growth phase.

  • PureGRAPH™ graphene has been successfully incorporated into a high volume application in the mining sector. 
  • A full scale mining reclaimer bucket was cast for an on-site trial with a multi-national mining company 
  • Test work has confirmed PureGRAPH™ readily disperses into the polymer resin used 
  • Further bucket linings will be cast and sold for use in northern Australia with a multi-national mining group 
  • PureGRAPH™ enhanced polymer liners for a range of associated applications will also be trialled 
  • This success with a graphene-enhanced bucket lining will open an important growth curve for graphene enhanced rubbers and composites
  • There are 12 buckets on the wheel for the machine these buckets are destined for, each with a capacity is 2.2 m3. The reclaimer has a nominal machine capacity is 12,000 tph and maximum capacity is 14,500 tph in bauxite.

 

newGen 

 

As announced in June 2018 FGR is working with newGen Group on equipment used in the mining industry to improve polyurethane liners to protect them from excessive abrasion and increase their useful life. 

 

Since then FGR and newGen have conducted various tests using PureGRAPH™ in polyurethane to determine the best suited PureGRAPH™ product and the optimum quantity to be added. These tests have demonstrated that the PureGRAPH™ product provides significantly increased flexural strength to the base polyurethane product. 

 

newGen have now cast a liner for a Sandvik reclaimer bucket using PureGRAPH™ 20 and are now working with FGR on the use of a PureGRAPH™ enhance polyurethane in other high volume mining applications in the iron ore industry where newGen are preferred supplier.

 

FGR Managing Director, Craig McGuckin, stated: “Achieving the creation of this bucket liner for a multi-national end user is a credit to Ben’s foresight and the team at FGR.” 

 

newGen’s Ben Walker stated: “We are pleased to be at the forefront of graphene use in mining materials. It has been excellent to work with the calibre of people at First Graphene in this march towards supplying our valued clients with ground breaking, high performance materials.”

PureGRAPH™ graphene powders are available with lateral platelet sizes of 20μm, 10μm and 5μm. The products are characterised by their low defect level and high aspect ratio. 

 

About Graphene 

Graphene, the well-publicised and now famous two-dimensional carbon allotrope, is as versatile a material as any discovered on Earth. Its amazing properties as the lightest and strongest material, compared with its ability to conduct heat and electricity better than anything else, means it can be integrated into a huge number of applications. Initially this will mean graphene is used to help improve the performance and efficiency of current materials and substances, but in the future, it will also be developed in conjunction with other two-dimensional (2D) crystals to create some even more amazing compounds to suit an even wider range of applications. 

 

One area of research which is being very highly studied is energy storage. Currently, scientists are working on enhancing the capabilities of lithium ion batteries (by incorporating graphene as an anode) to offer much higher storage capacities with much better longevity and charge rate. Also, graphene is being studied and developed to be used in the manufacture of supercapacitors which can be charged very quickly, yet also be able to store a large amount of electricity.
