In electrochemical ways, constant potential electrolysis technique and potentiodynamic technique have been applied. By using constant potential electrolysis technique polythiophene and polythiophene derivatives have been obtained in acetonitriletetrabutylammonium tetraflouroborate as solvent-electrolyte system at fifferent conditions. Platin plates electrodes were employed for both working and counter electrodes. Silver wire is used as a referance electrode. The effects of monomer concentrations, electrolysis potential, electrolysis period, electrolysis temperature and electrolytes types were investigated on characterization of polythiophene and polythiophene derivatives. The conductivies of polythiophene samples obtained under different conditions were measured ranging in between 2.76*10-5and 7.36*10-2 S/cm. On the other hand polythiophene and polythiophene derivatives were characterized also with some other techniques such as FTIR, TGA, SEM and CV. From FTIR spectrum, It has been observed that chemical structures of polythiophene and polythiophene derivatives obtained under different conditions did not change. Electrochemical stability and electrochemical reactivity were followed by using CV technique. Morphological maps of polymer samples were observed from SEM indication. Mass loss of polythiophene and polythiophene derivatives at 200 ºC, 400 ºC and 600 ºC are given in tabulated forms by using TGA termograms. Solubility tests for some polymer samples obtained from both chemical and electrochemical technique were done using various solvents. 2
