Conducting polymer blend (alloy) films of poly(pyrrole) or derivates w
ith the insulating matrix PVDF-C2F3H. were synthesized (produced) by e
lectrochemical polymerization of pyrrole or derivates on an electrode
covered with the insulating film. The optimizations of the electrochem
ical polymerization and of the conductivities of the materials were st
udied. There electrical behaviors were observed at low temperature. Th
e thermal stability of polypyrrole is improved in the high temperature
region when it is incorporated in the fluorinated copolymer.
