Electrochemical synthesis of poly(o-anisidine)/chitosan composite on platinum and mild steel electrodes

In this study, poly(o-anisidine)/chitosan composite film was electrochemically synthesized on the platinum and mild steel electrodes. Electrochemical synthesis of the composite film was carried out by cyclic voltammetry technique. The synthesized composite film was characterized by FT-IR, UV–Vis, cyclic voltammetry, SEM and TGA. The SEM micrographs showed that the composite film homogeneously covered the surfaces of platinum and mild steel electrodes. The TGA results proved that the composite film does not degrade until 648 °C while the poly(o-anisidine) film is decomposed between 190 and 432 °C. Also, electrochemical studies showed that poly(o-anisidine) and the composite films have good stability and electroactivity.
