▎ 摘 要
NOVELTY - Preparation of protective coating on metal copper surface comprises dissolving aniline monomer in dispersed liquid of graphene oxide; and depositing polyaniline/graphite oxide (PANI/GO) composite coating on surface of metal copper substrate by electrochemical method. USE - Preparation of protective coating on metal copper surface. ADVANTAGE - The method produces PANI/GO composite coating that can effectively improve corrosion resistance and conductivity of substrate. It has simple process and easy operation.
