Electrochemical Synthesis of PolyanilinePoly-O-Aminophenol Copolymers in Chloride Medium

الملخص EN

The copolymerization of o-aminophenol (OAP) and aniline (ANI) on Pt and ITO electrodes was studied using cyclic voltammetry in 0.1 M HCl/0.4 M NaCl solution.

The films were characterized by SEM, cyclic voltammetry, and UV-Vis spectroscopy.

The properties of the copolymer were compared with PANI and POAP films.

The results strongly suggest that the growth of PANI-POAP films does not consist of the simple buildup of layers of homopolymers on the electrode surface as a result of OAP or ANI oxidation products in the monomer mixture, but that a new conducting polymer is formed by copolymerization.
