First Graphene signs exclusive supply agreement with Steel Blue

Posted By Graphene Council, Wednesday, February 12, 2020
First Graphene Ltd, the leading global producer of advanced graphene products, has signed an exclusive supply agreement with Steel Blue, a major global manufacturer of work boots. Under the supply agreement, Steel Blue will exclusively source graphene and any other graphite or graphene products from First Graphene over a 2-year term.

First Graphene recently partnered with Steel Blue to develop an effective manufacturing process, with graphene being incorporated successfully into thermoplastic polyurethane masterbatches, used for the production of the soles and other components of safety boots. This work was followed by wear trials and independent product testing by Viclab Pty Ltd, one of Australia’s leading NATA accredited testing facilities. The results showed an increase in abrasion and tensile strength, potentially leading to extended product life, plus enhanced heat transfer and reduction in weight.

First Graphene’s Managing Director, Craig McGuckin, explains that, “The new supply agreement highlights the confidence that Steel Blue has in our PureGRAPH® materials and in our ability to deliver large volumes of graphene over an extended period. PureGRAPH® has the ability to help our customers throughout industry transform the characteristics of existing products and materials. For example, PureGRAPH® additives are a key enabler in taking elastomers, composites, coatings and concrete to new levels of performance and we’re actively working with customers in these sectors. As a result, we anticipate that the supply agreement with Steel Blue will be the first in a growing number to be signed during 2020.”

Chief Executive Officer, at Steel Blue, Garry Johnson, commented, “Steel Blue is committed to developing innovative solutions for our customers. We’re excited by the innovations we have developed with First Graphene. We look forward to bringing exciting new safety technologies to the global work boot market.”

First Graphene - Quarterly Activities Report

Posted By Graphene Council, Friday, January 31, 2020

First Graphene has continued to make substantial progress in its objective of commercialising the PureGRAPH® range of graphene products during the December quarter. PureGRAPH® has provided a range of improved performance characteristics in a number of products to which it is added.

The Company continues to maintain a strong working capital position, which will drive the growth of First Graphene with increased production efficiencies and higher manufacturing throughput, market development with new customers and novel graphene applications and global supply capabilities.

Steel Blue and First Graphene showcased safety boots at the Polymers in Footwear event in Berlin In November 2019 FGR and Steel Blue gave a joint presentation at the above exhibition and showcased PureGRAPH® enhanced safety boots. First Graphene Ltd and Steel Blue explained how PureGRAPH® had enabled the development of a range of unique boot component technologies and user benefits which have the potential to revolutionise the safety boot market.

The prototype boots have been manufactured using First Graphene’s PureGRAPH® graphene additives. Unlike competing formulations, this is available in high production volumes with non-aggregated, uniform-sized graphene; this ensures it disperses evenly in thermoplastic polyurethane (TPU) masterbatches.  The prototype boots incorporate PureGRAPH®-infused TPU soles and polyurethane foam innersoles and had undergone extensive laboratory testing in accredited laboratories.

Tests had been 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)

Steel Blue have continued to test different applications and processes, with ongoing measuring of outcomes by Viclab Pty Ltd. The collaboration led to the successful manufacturing of prototypes, and these are currently being wear trialled in a variety of working environments.

The new boot from Steel Blue incorporates innovative technology with new design solutions to provide significant improvements to safety footwear protection and comfort.

Positive Interim Results from Mining Industry Field Trials
In December, FGR was pleased to announce an update on the Armour-GRAPH™ bucket liner provided by newGen to a major Pilbara iron ore producer.

newGen had provided an Armour-GRAPH™ bucket liner to a major iron ore  producer for trial which contained PureGRAPH®20. The bucket had been in use for in excess of 12 weeks at the time it was inspected by the client for assessment of wear, with very pleasing results. The next assessment is due to be undertaken in January.

Preparations were underway to trial PureGRAPH® enhanced materials in equipment used by a second iron ore producer.

Continued Growth in Customer Engagement
Customer growth continued apace during the December quarter, with engagements in the UK, Europe, Asia and Australia markets. The Company’s focus continues to be in the development of elastomers and plastics and the composites industries as it is these markets which have the potential to generate the largest volume of sales.

Activities at the GEIC, Manchester,UK
The Company continues to make effective use of it’s presence as a Tier 1 partner at the Graphene Engineering and Innovation Centre, where the facilities are routinely used to host customer visits and the capabilities deployed to prepare PureGRAPH® dispersions for a range of customer evaluations; from TPU elastomers to coating precursors. The UK team have developed a strong relationship with the academic departments with active relationships with the Chemistry, Civil Engineering, and Composites & Textiles departments.

2019 – A Year in Review

The 2019 calendar year has seen FGR make considerable progress as the world’s leading graphene company. The Company has continued to automate its  production process, maintain its high-quality standards and develop its in-house product development and testing platform.

Customer engagement has accelerated as a result of the marketing efforts and the release of the Company’s B2B focussed website.

There has been extensive field testing by customers of the PureGRAPH® range of products, all of which have been successful and resulted in ongoing collaboration. That this process has not manifested itself in more extensive sales is the one area of disappointment. However, as previously stated by Warwick “The larger the organisation the longer the time frame that would typically extend beyond 12 months. Offsetting this though is the prospect of larger size sales.” The Board of Directors and Senior Management team see 2020 as the year in which FGR will achieve significant sales growth, having built a very solid base during 2019.

First Graphene's Strong Advances in VFD Development

Posted By 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, 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.’’

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

Posted By 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, 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, 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”.
