A renewable carbon fiber array ring-glassy carbon disk electrode was used for in-situ monitoring of conductivity and potential response of elec. conductive polymers during electrochem. redox process. Cyclic voltammetryof poly(3-methylthiophene) (I) and polythiophene (II) on the above electrode in acetonitrile solution of tetrabutylammonium perchlorate were given. Elec. conductivities of 90 to 3 ?10-4 S/cm and 40 to 3 ?10-4 S/cm were observed for I and II resp. during electrochem. redox process.

Key words: ELECTRODE, ELECTRIC POTENTIAL, GLASS CARBON, ELECTRIC CONDUCTANCE, CARBON FIBERS, CONDUCTING POLYMER, ELECTROCHEMICAL METHOD
