Poli(anilin-co-pirol) (PANI-co-PPy) ve poli(anilin-co-N-metilpirol) (PANI-co-PNMP) kopolimer filmler ZnFe kaplı karbon çelik (KÇ/ZnFe) elektrot yüzeyine elektrokimyasal olarak sentezlenmiştir. ZnFe kaplama için galvanostatik yöntem, kopolimer kaplamalar için ise dönüşümlü voltametri yöntemi kullanılmıştır. PANI-co-PPy film 0.05 M anilin + 0.05 M pirol içeren 0.3 M okzalik asit çözeltisinde sentezlenmiştir. PANI-co-PNMP film ise 0.05 M anilin + 0.05 M N-metilpirol içeren 0.3 M okzalik asit çözeltisinde sentezlenmiştir. PANI-co-PPy ve PANI-co-PNMP kopolimerleri ile kaplı elektrotlar doğrusal taramalı voltametri, elektrokimyasal empedans spektroskopisi ve anodik polarizasyon teknikleriyle karakterize edilmiştir. Doğrusal taramalı voltametri sonuçları kopolimer kaplamaların altında ZnFe alaşımının bulunduğunu göstermiştir. Elektrokimyasal empedans spektrsokopisi bulguları PANI-co-PNMP kaplı KÇ/ZnFe (KÇ/ZnFe/PANI-co-PNMP) elektrodun polarizasyon direncinin (Rp) PANI-co-PPy kaplı KÇ/ZnFe (KÇ/ZnFe/PANI-co-PPy) elektroda göre daha yüksek olduğunu ortaya koymuştur. Anodik polarizasyon eğrileri en düşük akım ve en yüksek korozyon potansiyeline sahip elektrodun KÇ/ZnFe/PANI-co-PNMP elektrot olduğunu göstermiştir.

Poly(aniline-co-pyrrole) (PANI-co-PPy) and poly(aniline-co-N-methylpyrrole) (PANI-co-PNMP) copolymer films were electrochemically synthesized on the ZnFe coated carbon steel (KC/ZnFe) electrode surface. Galvanostatic method is used for ZnFe coating and cyclic voltammetry method is used for copolymer coatings. PANI-co-PPy film was synthesized in 0.30 M oxalic acid solution containing 0.05 M aniline + 0.05 M pyrrole. PANI-co-PNMP film was synthesized in 0.30 M oxalic acid solution containing 0.05 M aniline + 0.05 M N-methylpyrrole. Electrodes with coated PANI-co-PPy and PANI-co-PNMP copolymers were characterized by linear sweep voltametry, electrochemical impedance spectroscopy and anodic polarization techniques. The linear sweep voltammetry results indicated that the ZnFe alloy was under the copolymer coatings. The electrochemical impedance spectroscopy findings revealed that the polarization resistance (Rp) of the PANI-co-PNMP coated KC/ZnFe (KC/ZnFe/PANI-co-PNMP) electrode was higher than that of the PANI-co-PPy coated KC/ZnFe (KC/ZnFe/PANI-co-PPy) electrode. The anodic polarization curves showed that the electrode with the lowest current and highest corrosion potential is the KC/ZnFe/PANI-co-PNMP electrode.
