ELECTROCHEMICAL PREPARATION AND CHARACTERIZATION OF CONDUCTING COPOLYMERS - POLY(ANILINE-CO-N-BUTYLANILINE)

The solubility and processability of conducting polymers are, in many cases, the most important properties for their wide applications. To o btain a soluble conducting polymer, a series of poly(aniline-co-butyla niline) copolymers, from the monomers aniline and N-butylaniline, has been prepared in aqueous solution by electrochemical methods. The mech anism of the electropolymerization has been studied, The ratio of the two monomers has a great influence on the copolymerization process and the electrochemical behavior of the copolymers. The copolymers have b een characterized by electrochemical and spectroscopic methods. Their electrochemical properties were compared with those of homopolymers, p olyaniline and poly (N-butylaniline).
