 A new class of semicrystalline terpolymers consist of vinlylidene fluoride (VdF),
trifluorethylene(TrFE), and chlorofluorethylene (CFE), were prepared by a suspension
polymerization. The terpolymer was crossliked with 2,4,4-trimethyl-1,6-hexanediamine in order
to improve insolutility and fusibility of the terpolymer. Thin films of the crosslinked terpolymer
(20~50§-    ) were prepared by a solution casting. A conducting polymer, polypyrrole (PPy) was
synthesized on the surface of the terpolymer layer by using a chemical oxidation polymerization
technique.       A    room     temperature     ionic     liqids    (RTIL),     1-buthyl-3-methyl
imidazoliumbis(trifluoromethylsulfonyl)imide (BMITFSI), was absorbed into the terpolymer
film. The cyclic voltammetry responses and the redow switching dynamics of PPy in P(VdF-
TrFE-CFE) terpolymer/BMITFSI solid polymer electrolyte were studied. The displacement of
actuator was measured by laser beam radiation.
