▎ 摘　　要

NOVELTY - Method for preparing an anticorrosive coating, involves providing graphene oxide aqueous solution; dispersing the conductive polymer monomer and the doped organic matter in the graphene oxide aqueous solution to obtain an electropolymerization electrolyte; and adding the metal bipolar plate to the electropolymerization electrolyte and passing an electric current to form an anticorrosive coating on the surface of the metal bipolar plate. USE - The method is used for preparing an anticorrosive coating, which is used for metal anticorrosion (all claimed). ADVANTAGE - The method inhibits the generation of passivation film, makes the conductivity of the anti-corrosion coating more excellent, hinders the ion migration process in electrochemical corrosion, improves the corrosion resistance of metal bipolar plates, and enhances the barrier effect of graphene oxide.
