Abstract A two-step electrosynthesis of polypyrrole film （Ppy） on 1Cr18Ni9 stainless steel and Pt substrates was performed based on the self-catalysed property of Ppy synthesis， and smooth conductive polymer film was obtained. The redox character of Ppy and corrosion behavior of stainless steel protected by Ppy film in 3.5% NaCl solution were investigated.Results show that the reduction of Ppy contains two processions including anion de-dopping and cation insertion， and that reversible oxidation （doping） can only occur at low potential. It is con?鄄firmed that stainless steel corrosion can be inhibited effectively by Ppy film and the physical barrier is not the major factor of corrosion protection.It is possible that Ppy coating has a catalytic effect on passivation of metal with protective oxide layer， and corrosion could be inhibited.
