Graphene 3D Lab adds graphene-silver epoxy to its G6-Epoxy product line

Graphene 3D Labs logoGraphene 3D Lab, a leader in the development, manufacturing and marketing of proprietary composites and coatings based on graphene and other advanced materials, has announced an addition to its G6-Epoxy line of adhesives. This new product, G6E-GSTMepoxy, is a highly electrically conductive adhesive based on the combination of graphene and silver additives. It reportedly has a volume resistivity as low as 0.0001 Ω·cm and can be cured at room temperature or more rapidly at elevated temperatures. G6E-GSTM bonds well to a wide variety of substrates including metals, composites, ceramics, and glass.

The graphene filler is said to enhance the electrical conductivity of the epoxy and prevent the propagation of cracks, improving the material’s durability and fatigue resistance. This is especially important when bonding dissimilar materials subjected to rapid temperature variations. This feature improves impact resistance of the bond and also helps mitigate potential damage caused by vibration.

Haydale signs joint development agreement with Huntsman Advanced Materials

Haydale logoHaydale Graphene Industries announced that Haydale Composite Solutions (HCS), its wholly owned subsidiary, has formally entered into a joint development agreement with Huntsman Advanced Materials. This agreement has resulted from the successful preliminary work jointly undertaken with Huntsman, to develop a range of graphene enhanced resins to complement its current product range.

The agreement provides Huntsman with the exclusive worldwide rights to market, distribute and sell a range of its resins enhanced with Haydale's functionalised graphene. This will include ARALDITE epoxy resins. The agreement will allow Huntsman to purchase Haydale's graphene enhanced masterbatches for use in the fields of composites and adhesives. Huntsman has also agreed to work exclusively with HCS to further develop graphene enhanced masterbatches with specific targeted performance characteristics.

Russian team makes graphene with high stability under ozonation, with great potential for nanoelectronics

Scientists from Russia's National Research Nuclear University MEPhI have succeeded in producing graphene with a very high stability to ozonation using high-temperature sublimation of silicon carbide (SiC). The resulting graphene maintains contact with ozone for more than 10 minutes (while ordinary graphene loses its properties after only three or four minutes under such conditions). These results may hold great potential for the development of nanoelectronics.

To further examine the effects, scientists from Greece, France and Sweden were brought onto the team. Using computer modeling, the experts were able to figure out why SiC-graphene was more stable under the impact of aggressive oxygen free radicals. The new graphene's abnormal stability appeared to be associated with the low roughness of epitaxial graphene on SiC-substrate (epitaxy is a natural buildup of one crystalline material upon the surface of another).

Versarien announces successful completion of graphene composites project with the NGI

Versarien LogoVersarien has announced the successful completion of a grant funded project focused on graphene enhanced carbon fibre composites with the National Graphene Institute (NGI) at The University of Manchester.

Extensive trials of the graphene produced by Versarien’s subsidiary, 2-DTech, by an NGI team, in carbon fibre composite products, has demonstrated the benefit of adding graphene, particularly with regard to significantly enhancing the strength of the structure.

A graphene-enhanced vehicle unveiled in Manchester

A vehicle made with graphene in its bodywork has recently been unveiled in Manchester. The car was made by Briggs Automotive Company (BAC) and graphene is said to be used in the car's panels. The BAC Mono spearheads an exhibition to highlight the future of graphene technology.

The BAC Mono has reportedly been road-tested and is being displayed at the National Graphene Institute in Manchester as part of the Science in the City festival from July 22-29. James Baker, graphene business director at The University of Manchester, said: "The graphene car is an excellent example of how graphene can be incorporated into existing products to improve performance".
