Abstract
The electrosynthesis of both the polymer and copolymer were carried out from 2, 2'-bithiophene and 3-bromothiophene monomers using galvanostatic and potentiodynamic techniques. The most stable films were obtained using the galvanostatic technique in nitrobenzen solvent and TBAPF6 as supporting electrolyte. A comparison relaxation study was made between the prepared copolymer and homopolymer films using the cyclic voltammetric technique in different solvents. Several studies were performed to determine the solvent effect, monomer concentration ratio, electrocopolymerization techniques and temperature which give a lower relaxation time.
