Nanaotechnology world: Graphene: a ‘miracle material’ in the making – The Guardian

Published 17 August 2011

Many scientists believe the remarkable properties of graphene could lead to the development of technology such as super-fast computers, flexible mobile phones and even transparent planes among other things. But will the nanomaterial live up to the hype?

…Why all the excitement? When graphite is broken down into graphene, the ultra-thin flakes take on unusual and exciting new properties. Three million of these sheets stacked on top of one another would stand just one millimetre high, and yet graphene is the strongest material ever measured, some 200 times stronger than steel. It is also the most conductive. At the atomic level, it resembles a chicken wire lattice of carbon molecules that is so fine that not even a hydrogen molecule can pass through it.
