THE PREPARATION OF POLYPYRROLE AND POLYTHIOPHENE IN THE PRESENCE OF FERROCENE DERIVATIVES

Polypyrroles doped with electroactive materials such as ferrocenemonosulfonate, ferrocenedisulfonate, and poly(vinylferrocenesulfonate) were PrePared and their electrochemical properties were studied. Polypyrrole doped with poly(vinylferrocenesulfonate) was examined for the rechargeable battery electrode material. A fairly high energy density (384 Wh/Kg) was obtained for the lithium/polypyrrole-poly(vinylferrocenesulfonate) battery. A facile release of ferrocenemonosulfonate from polypyrrole was observed during redox cycles whereas poly(vinylferrocenesulfonate) in the polypyrrole matrix was retained for more than hundreds of cycles. Combined with the smooth and uniform film forming property, polypyrrole doped with poly(vinylferrocenesulfonate) is a promising electrode material for the rechargeable battery.
