Descrição: Double strands of polyaniline (PAn) and poly( o -anisidine) (POAn) with poly(acrylic acid- co -acryl amide) (PAA- co -AA) were successfully prepared on steel as undercoating, by immersion of the pretreated surfaces into a PAn: (PAA- co -AA) and POAn: (PAA- co -AA) saturated DMF solution separately. The undercoatings formed on the steel were characterized by Fourier transform infrared spectroscopy (FTIR) techniques. A commercial paint (Nippon Paint, nonadded Chrome) was used as topcoating. Electrode/electroactive polymer/paint/electrolyte system was studied by electrochemical impedance spectroscopy (EIS). The EIS studies show that during the first 18 days immersion time in 3.5% solution of NaCl, paint/PAn coating has better corrosion resistance than paint/POAn coating while in the final week of immersion time, the pore resistance ( R po ) and coating capacitance ( C c ) of paint/POAn are higher and lower than the paint/PAn, respectively.
