Poly(aniline-co-N-methylpyrrole) and poly(N-methylpyrrole-co-N-methylaniline) copolymers were synthesized on the ZnNi-coated carbon steel (CS/ZnNi) electrode surface by cyclic voltammetry method. Copolymer film-coated electrodes were characterized by anodic polarization, linear sweep voltammetry and electrochemical impedance spectroscopy. It was determined that there was a ZnNi alloy underlying the copolymer films synthesized by linear sweep voltammetry. Anodic polarization curves showed that the current values of the poly(N-methylpyrrole-co-N-methylaniline) coated CS/ZnNi electrode were lower than the poly(aniline-co-N-methylpyrrole) coated CS/ZnNi electrode. Electrochemical impedance spectroscopy results showed that the polarization resistance of the poly(N-methylpyrrole-co-N-methylaniline) coated CS/ZnNi electrode was higher than the poly(aniline-co-N-methylpyrrole) coated CS/ZnNi electrode after a long waiting time of 168 hours in a corrosive environment.

Öz

Poli(anilin-ko-N-metilpirol) ve poli(N-metilpirol-ko-N-metilanilin) kopolimerleri ZnNi kaplı karbon çelik (CS/ZnNi) elektrot yüzeyine döngülü voltametri yöntemiyle sentezlenmiştir. Kopolimer film kaplı elektrotlar anodik polarizasyon, doğrusal taramalı voltametri ve elektrokimyasal empedans spektroskopisi ile karakterize edilmiştir. Doğrusal taramalı voltametri ile sentezlenen kopolimer filmlerin altında ZnNi alaşımı bulunduğu belirlenmiştir. Anodik polazrizasyon eğrileri poli(N-metilpirol-ko-N-metilanilin) kaplı CS/ZnNi elektrodun akım değerlerinin daha düşük olduğu göstermiştir. Elektrokimyasal empedans spektroskopisi korozif ortamda uzun bekleme süresi olan 168 saat sonunda poli(N-metilpirol-ko-N-metilanilin) kaplı CS/ZnNi elektrodun polarizasyon direncinin Poli(anilin-ko-N-metilpirol) kaplı elektroda göre daha yüksek olduğunu göstermiştir.
