Electrosynthesis of Bromothiophene and Thiophene as Conducting Copolymer and Study of their Electrochemical Relaxation

Abstract

The electrosynthesis of the copolymer of 3-bromothiophene and thiophene has been investigated 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 study was performed for the prepared copolymer and homopolymer films that were subjected to relaxation studies using the cyclic voltammetric technique in different solvents. The effect of solvent, monomer concentration ratio, electrocopolymerization techniques and temperature on the relaxation time were investigated.
