▎ 摘　　要

A polyaniline-reduced graphene oxide composite (PANI-rGO) coating was electrochemically deposited on 5083 Al alloy by potentiostatic method. The coating was characterized by stereoscopic microscopy, SEM, TEM, FTIR and XPS measurements. The anticorrosion performance of PANI-rGO coating was studied using potentiodynamic polarization and EIS measurements in aqueous 3.5% NaCl solution. Results obtained show that the presence of rGO facilitated electro-polymerization of PANI and accelerated the passivation of the Al alloy. The PANI-rGO coating presented good corrosion protection properties.
