Brittle, expensive smartphone screens may soon be a thing of the past, thanks to scientists who have combined silver and graphene to develop environment friendly, flexible displays that match the performance of existing technologies at a fraction of the cost. Indium tin oxide, which is currently used to make smartphone screens, is brittle and expensive. Scientists at the University of Sussex in the UK combined silver nanowires with graphene - a two dimensional carbon material. "While silver nanowires have been used in touch screens before, no one has tried to combine them with graphene," said Alan Dalton from the University of Sussex. It would be relatively simple to combine silver nanowires and graphene in this way on a large scale using spraying machines and patterned rollers," he said.
