▎ 摘  要

NOVELTY - Producing reduced graphene oxide film, comprises: (a) preparing a graphene oxide film; and (b) rapidly expanding and reducing the graphene oxide film in a physically shielded space along the direction of expansion. USE - The film is useful to produce carbon-based materials for battery, supercapacitor electrode, and high-porosity sub-materials of energy storage system. ADVANTAGE - The method: provides thin reduced graphene oxide film with a desired thickness, flexibility, and high quality, without causing cracking during expansion of graphene oxide; and can variously adjust the surface shape of the film to a simple process without causing defects of the produced reduced graphene oxide film.
