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

Polypyrroles doped with electroactive materials such as ferrocenemonos ulfonate, ferrocenedisulfonate, and poly(vinylferrocenesulfonate) were PrePared and their electrochemical properties were studied. Polypyrro le doped with poly(vinylferrocenesulfonate) was examined for the recha rgeable battery electrode material. A fairly high energy density (384 Wh/Kg) was obtained for the lithium/polypyrrole-poly(vinylferrocenesul fonate) battery. A facile release of ferrocenemonosulfonate from polyp yrrole was observed during redox cycles whereas poly(vinylferrocenesul fonate) 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 e lectrode material for the rechargeable battery.
