Graphene touch

摘要

A touch-screen with transparent electrodes made from graphene - single layers of carbon atoms - could be thinner, cheaper and more durable than today's devices that use indium tin oxide. But it has proved hard to manufacture these transparent films efficiently on a large scale.rnNow Byung Hee Hong, Jong-Hyun Ahn at Sungkyunkwan University in Suwon, South Korea, and their colleagues have made such films (pictured) using a scalable industrial manufacturing process and incorporated them into a touch screen.
