Abstract

Electrochemical polymerization of N-vinylcarbazole was carried out in a solution of tetramethyl ammonium chloride in dichloroethane at a constant current. The polymer yields increase with increasing concentration of monomer, impressed current level andelectrolysis time. The inhibition of polymer formation by a free radical scavenger, 2-2-diphenyl-1-picrylhydrazyl supports a free radical mechanism. The free radical species are generated in situ during the electrolysis of polymerizing mixture. Cyclic voltammograms demonstrate the polyvinylcarbazole formed electrochemically in a solution of (C4H5)4NSbC16 or (C4H9)4NClO4 in DCE undergoes oxidation-reduction states. The polymerization of NVCZ resulted in the formation of cross linked conductive polymers on the anode. The conductivity was found to be about 10−6 scm−1.
