Engineering Materials Live exhibitor introduces new, ‘green’ graphene

Engineering Materials Live exhibitor Goodfellow has introduced an ultra-pure “green” graphene material, which is guaranteed metal-free and therefore uniquely suitable for use in metal-sensitive processes and applications. The graphene is produced by means of a highly scalable process that involves breaking methane gas (CH4), into hydrogen and elemental carbon atoms in a plasma reactor. The carbon atoms are then recombined into graphene sheets in the hydrogen atmosphere. Elapsed time from the methane gas entering the plasma reactor to the point when graphene is formed is quick - typically less than a second. The speed and cost effectiveness of this ‘green’ mass production method promises to make graphene readily available to a wide range of industries with a minimal impact on the environment.

The graphene nanoplatelets produced by this innovative process are very thin and slightly crumpled, and they do not stack (unlike exfoliated materials), thus ensuring optimal electrical, thermal and mechanical performance. These characteristics also make this easy-to-use product an extremely good nanofiller which is suitable for electronic inks, polymers, metal composites and coating.

Goodfellow offers both multi-layer graphene (and predominantly single-layer graphene) obtained through the green production process described above, and these materials, together with so many others offered by Goodfellow, can be seen, examined and discussed on the company’s stand at Engineering Materials Live on March 12th.

Entry to the Engineering Materials Live event is free of charge by pre-registration. The event takes place at the acclaimed British Motor Museum, located adjacent to the Aston Martin and JLR plants at Gaydon south of Warwick and just 1 minute from the M40. There is abundant free parking, and for visitors arriving before 1030, a free bacon roll and brew too. Tea and coffee is provided free of charge all day at the event, and pre-registered exhibition visitors can also visit the superb Museum, with almost 300 fascinating cars on show, free of charge too (standard adult entry fee otherwise is £14.50).
