▎ 摘  要

NOVELTY - A graphene foam film has a continuous rhombic three-dimensional porous structure. USE - Graphene foam film used in energy storage, flexible electronic sensors, smart clothing, electromagnetic shielding cover, insulation and noise shielding applications (all claimed). ADVANTAGE - The graphene foam film has continuous three-dimensional porous structure, excellent conductive performance, low density, mechanical properties, and can be prepared quickly using small direct current voltage. The method is simple, economical and is easily scalable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene oxide foam film, which involves dispersing graphene oxide in water, ultrasonically processing to obtain graphene oxide dispersion, transferring the graphene oxide dispersion into hydrophobic plastic culture dish and heating to obtain graphene oxide film, reducing the graphene oxide film using hydroiodic acid and washing to obtain graphene film.
