%X The polypyrrole(PPy)film was synthesized by cyclic voltammetry method on 304 stainless steel(304SS).Its corrosion performance in 3.5 wt% NaCl solution is then investigated by measurements of open circuit potential(OCP),potentiodynamic polarization cureves and electrochemical impedance spectroscopy(EIS).Results show that the PPy film may shift the corrosion potential of steel from 60mV to positive direction,and decrease the corrosion current density from 10-6 A/cm2 to 10-7 A/cm2.The mechanism of good corrosi...
