Abstract :
The copolymerization of thiophene and pyrrole thin films synthesized by using a double discharge technique which has a fast filamentary discharge formed from the superposition of an ordinary low-pressure dc glow discharge and a high-current pulsed one is presented. Quartz glass substrates were coated at a pressure of 0.8 mbar and 19-kV pulsed and 2-kV dc potentials. The analysis of functional groups by FTIR spectrometry showed that the molecular structure of the copolymerized thin films with the filamentary discharge part almost preserves the conventional polymeric structure.
