The Institution of Mechanical Engineers has recently published an article titled “Graphene – the not-so wonder material?”. Our Executive Director, Professor Krzysztof Koziol, features in this article and discusses the challenges to overcome for the “wonder material” to go mainstream.
In the article, Krzysztof discusses the need for a large scale and impurity free graphene manufacture method, as well as our proprietary graphene making technology which “uses a unique plasma reactor to first break the feedstock [methane gas] into hydrogen and elemental carbon atoms, and then these atoms are recombined into graphene sheets by floating them in the hydrogen atmosphere. The time it takes for methane gas to enter the plasma reactor to the point when graphene is formed is less than a second.”
Some of other excerpts from Krzysztof’s interview include:
- “When graphene was first isolated by the team in Manchester, it came from high-quality graphite but was peeled off layer by layer using tape. This is a perfectly good method to get a few flakes in a lab environment, but not really suitable for significant volume generation.”
- “Although mechanically exfoliated graphene, like that produced by the Scotch tape technique, has the best physical properties, individual flakes acquired through this method are too expensive for bulk production”.
- “It could be five, 10 or 20 years before the graphene revolution arrives on shelves for consumers to buy. But they will come, it’s just a question of when. Graphene will not just remould manufacturing processes, it will also improve the performance of everyday objects”.
