It has become almost a cliché to call graphene the “wonder material”, but this super-thin 2D honeycomb array of carbon atoms boasts some enviable electronic and mechanical properties. Apart from being the strongest material ever measured, graphene is also the stiffest and has an electrical current density a million times that of copper. Hardly surprising then that companies and institutes around the world have been stumbling over themselves to carry out research into this material, which was first isolated through Nobel-prize-winning work at the University of Manchester in the UK in 2004.
