A self-assembled 1-dodecanethiol film assisted with the preferential adhesion of polydopamine was prepared on the non-etching 304 stainless steel surfaces by a simple dip-coating method.The formation and surface structure of the film were characterized by water contact angle measurement,atomic force microscopy(AFM),and X-ray photoelectron spectroscopy(XPS).The corrosion behavior of the complex films was evaluated by Tafel polarization curve and electrochemical impedance spectroscopy(EIS).The excellent corrosion resistance property could be attributed to the compact hybrid film structure and superior seawater stability for modified 304 stainless steel surface.
