▎ 摘　　要

Graphene oxide (GO) holds tremendous potential for large-area electronics, high strength and conducting fillers in composites, and high-surface-area electrodes for energy storage. Graphene oxide for such applications will require manufacturing methods that are industrially compatible but also preserve its unique properties. Recent work by Korkut et at describes a promising new scheme for continuous processing of colloidal suspension of GO into tapes that are meters long and tens of micrometers thick. Tapes of restacked graphene sheets exhibit graphite-like mechanical robustness and electrical conductivity but retain the high surface area and flexibility of graphene.
