▎ 摘　　要

NOVELTY - Preparing cellulose/graphene oxide composite film comprises mixing cellulose solution dissolved in organic alkali and graphene oxide dispersion solution dissolved in organic solvent, vacuum drying, adding coagulation bath, hot pressing and drying. USE - The method is useful for preparing cellulose/graphene oxide composite film. ADVANTAGE - The film has higher mechanical property, thermal stability, and reduces the composite film permeability coefficient.
