Bu çalışmada, poli(pirol-ko-o-aminofenol)/kitosan kompozit filmleri platin elektrot yüzeyinde farklı mol oranlarındaki (pirol:o-aminofenol; 8:2, 6:4, 1:1, 4:6 ve 2:8 ) çözeltilerde elektrokimyasal yöntemle sentezlenmiştir. Sentezlenen kompozit örnekleri FT-IR, dönüşümlü voltammetri (CV), dijital fotoğraf ve SEM görüntüleri teknikleri kullanılarak karakterize edilmiştir. Sentezlenen kompozit filmlerinin SEM görüntüleri incelendiğinde monomer oranı değiştikçe kompozit örneklerinin yüzey yapısının değiştiği sonucuna varılmıştır.Platin elektrot yüzeyine kaplanmış kompozit filmlerin elektrokimyasal davranışları incelendiğinde dönüşümlü voltamogramlarda ileri ve geri çevrimlerde ciddi akım değişimlerinin olmadığı görülmüştür. Bu sonuca göre kompozit filmlerinin elektrokimyasal olarak yüksek bir kararlığa sahip olduğu belirlenmiştir. Bunun yanında pirol miktarı en yüksek olan kompozit örneğinin (8:2) voltamogramında gözlenen yüksek kapasitif akım değerleri bu kompozit filminin elektrokimyasal kararlılığının en iyi seviyede olduğunu göstermiştir.

Electrochemical Synthesis and Characterization of Poly(Polypyrrole-co-o-aminophenol)/chitosan Composite Films in Solutions with Different Monomer Ratios

Öz

In this study, poly(pyrrole-co-o-aminophenol)/chitosan composite films were synthesized by electrochemical method in solutions of different molar ratios (pyrrole: o-aminophenol; 8:2, 6:4, 1:1, 4:6 and 2:8) on the platinum electrode surface. The synthesized composite samples were characterized using FT-IR, cyclic voltammetry (CV), digital photography and SEM imagery techniques. When the SEM images of the synthesized composite films were examined, it was concluded that the surface structure of the composite samples changed as the monomer ratio changed. When the electrochemical behavior of the composite films coated on the platinum electrode surface was examined, it was observed that there were no serious current changes in the forward and reverse cycles in the cyclic voltammograms. According to this result, it was determined that the composite films had a high electrochemical stability. In addition, the high capacitive current values observed in the voltammogram of the composite sample with the highest pyrrole content (8:2) showed that the electrochemical stability of this composite film was at the best level.
