▎ 摘　　要

NOVELTY - Continuous preparation of graphene oxide nanoplatelets involves using a flexible graphite coil, strip or carbon fiber wire, as raw material and subjecting to two step treatments e.g. electrochemical intercalation and electrolytic oxidation stripping using drive of feeding device to obtain oxidized graphene nanoplatelets dispersed in an electrolytic solution, and filtering, cleaning and drying to obtain graphene oxide powder material. USE - Continuous preparation of graphene oxide nanoplatelets (claimed). ADVANTAGE - The method provides graphene oxide nanoplatelets having not having metal impurity. The oxidation degree of graphene is controllable. The method is continuable and automatable. The method is safe and has low emissions.
