▎ 摘　　要

NOVELTY - Microwave-sol-gel process preparation of graphene film comprises using scale graphite powder as raw material, performing microwave treatment to obtain expanded flake graphite powder, using expanded flake graphite powder as precursor and small molecular amine as intercalation agent, adding ester solvent, peeling off intercalation layer to form graphene sol, aging graphene sol, forming on the substrate and drying. USE - Method for carrying out microwave-sol-gel process preparation of graphene film. ADVANTAGE - The method is simple and easy to control and low equipment and raw material cost.
