Abstract：The petrochemical equipment is subjected to electrochemical corrosion under the circumstance of which there are many chemical substances such as acid,alkali and salt. For the above electrochemical corrosion problems, using conductive polymer composite coating to resist corrosion of steel was put forward in this paper. The three kinds of anti-corrosion mechanism of the polyaniline coating in details were discussed, including metal oxide passivation,shielding effect and corrosion inhibition effect.A range of polyaniline and polyaniline composite coating and the application of the anticorrosion on steel were summarized, the application of polyaniline/inorganic composite coating was emphasized and the research trend of polyaniline coating was prospected. Polyaniline composite coating,especially binary and multi-components composite coating and the corrosion mechanism of composite coating will be the trend of future research and development.The preparation of polyaniline composite coating and corrosion protection study in complex environment will provide the reference to the application of that in a complex environment.
