摘要：
Polyaniline and polyaniline-graphene nanocomposite films were electrochemically deposited by cyclic voltammetry on 310 stainless steel electrode. The corrosion resistance of polyaniline and polyaniline-graphene nanocomposite covered 310 stainless steel substrates was estimated using potentiodynamic polarization and electrochemical impedance spectroscopy techniques in 5000 ppm NaCl aqueous solution at room temperature. Potentiodynamic polarization results show, which corrosion potentials shift to anodic regions in the presence of polyaniline-graphene nanocomposite compared to the pure aniline film. The electrochemical measurements also indicated that the inhibition efficiency for polyaniline-graphene nanocomposite and polyaniline are about 97 % and 73 %, respectively.
