Abstract
Conducting polymers, particularly poly(p-toluidine) (PPT) and its copolymer films with poly(o-aminophenol) [poly(PT-co-OAP)], have gained significant attention due to their diverse applications in batteries, electronic devices, sensors, etc. The copolymers were prepared using electrochemical method using cyclic voltammetry on an indium tin oxide (ITO) coated glass plate immersed in a solution of 1 M HCl. The influence of the monomer ratio on the resulting copolymerization and electrochemical behaviour was also investigated. Additionally, a possible mechanism for Poly(PT-co-OAP) formation in an acidic medium is also deduced. The synthesized copolymers were thoroughly characterized using IR, UV-Vis, PXRD, SEM and conductivity analysis.
