Electrochemical polymerization and in situ FTIRS study of conducting polymers obtained from o-aminobenzoic with aniline at platinum electrodes

The electrochemical copolymerization of o-aminobenzoic acid with aniline (ANI) was carried out on platinum electrodes in perchloric acid aqueous medium by cyclic scanning of the potential. Electrochemical homopolymerization of o-aminobenzoic acid was also done. Experimental results showed that the polymers are formed in all cases and the presence of aniline promoted markedly the growth of the rate of copolymerization. tained polymer films have been characterized by cyclic voltammetry and in situ Fourier transform infrared (FTIR) spectroscopy. The mechanism of the electrochemical polymerization reaction has been discussed.
