Graphene patchwork

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 al.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.
