ELECTROPOLYMERIZATION OF ANILINE DERIVATIVES IN NONAQUEOUS SOLUTION WITHOUT A PROTON DONOR

The initial formation of poly(aniline) and its derivatives was investi gated for the electropolymerization of anilines in several non-aqueous solutions without proton donor to prepare the films effectively. In t his study, 1,2-dichloroethane, acetonitrile, propylene carbonate and t etrahydrofuran were employed as solvent. The donor number of the solve nt affects the deprotonation of the cation radical of the monomer form ed, and the dimer and products, and the dielectric constant of the sol vent affects chain propagation during the electropolymerization of ani lines respectively. 1,2-Dichloroethane is revealed to be a more effect ive solvent than the others used in this study to prepare electroactiv e and soluble poly(aniline)s with head-to-tail structure.
