in fluorosulfonic acid (FSO3H)/acetonitrile medium using potentiostatic techniques. Adherent
and homogeneous SPPy films were obtained. The corrosion behavior of stainless steel with
sulfonated PPy coatings in 0.5 M hydrochloric acid solutions, were investigated by
potentiodynamic polarization technique, open circuit potential–time curves and
electrochemical impedance spectroscopy technique (EIS). It was found that the sulfonated …
