The graphene challenge

'Scratching graphite is a great proof-of-concept method that gives high-quality graphene for laboratories - but it won't work for industrial applications,' says Geim. The only commercial supplier of graphene is Graphene Industries, a spin-out company from the University of Manchester, UK.

Graphene Jacket

Graphene is simply the thinnest possible layer of graphite, the stuff used to make pencils. When graphite is reduced to a single layer of carbon atoms arranged in a hexagon formation, it turns into a supermaterial unlike anything ever known before – it's so strong and so stretchy that the fibres of a spider web coated in graphene could catch a falling plane.
