▎ 摘　　要

NOVELTY - A porous graphene thin film preparing method involves mixing a dispersion liquid of graphene and a dispersion liquid of particulate matter to form a graphene/particulate mixed thin film, allowing the graphene/particulate mixed thin film to film-forming treatment to form a graphene/particle mixed film, and removing the graphene/particulate matter from the mixed film to form a porous graphene film. USE - Method for preparing porous graphene thin film for electronic product (claimed). ADVANTAGE - The method enables preparing porous graphene thin film with high specific surface area and excellent conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a porous graphene thin film prepared by the method.
