▎ 摘　　要

NOVELTY - The preparation of graphene/conductive polypyrrole composite film involves adding 1-5 mg/ml graphene oxide solution, ultrasonically dispersing, placing in an open container, taking pyrrole monomer into another open container, placing two containers in a closed cover, making pyrrole monomer to be volatile in the closed cover, contacting resulting vapor phase monomer with oxidized graphene solution, carrying out oxidation-reduction reaction at the interface of two phases, and carrying out original oxidation reaction of graphene solution surface to generate a layer of black film. USE - Preparation method of graphene/conductive polypyrrole composite film used for anticorrosion of metal. ADVANTAGE - The graphene/conductive polypyrrole composite film has excellent anticorrosive property.
