The worm turns - into graphene

摘要

Chinese scientists have found a new route to high-quality graphene sheets for making flexible electronics.rnHongwei Zhu and co-workers from Tsinghua University in Beijing developed a three-step process to synthesise the one atom-thick carbon sheets from worm-like expanded graphite (WEG). WEG consists of a tall stack of graphene sheets, expanded, but not fully separated into individual layers. Graphene is expected to eventually replace silicon in a revolutionary new breed of flexible electronics for applications including smart clothing, for example, health-monitoring sensors embedded in fabric, and foldable displays.
