▎ 摘　　要

NOVELTY - Flame reduction of graphene oxide film comprises reducing by flame firing, so that capillary gas channels are formed in the graphite oxide film body in the graphene oxide film. USE - The method is useful for flame reduction of graphene oxide film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene film comprising the graphene oxide film using reduction treatment, performing high temperature thermal reduction, and compacting to obtain the graphene film.
