▎ 摘　　要

NOVELTY - A monomer, polymerization initiator and graphene are reacted to obtain polymer-graphene composite. The composite is dispersed in a solvent to obtain composite mixture. The composite mixture is coated on a substrate in the presence of a gas and the solvent is evaporated to obtain a film. The film is heat treated to obtain porous graphene film. USE - Manufacture of porous graphene film. ADVANTAGE - The porous graphene film has high strength, favorable thickness and is manufactured easily within a short period of time.
