    Abstract

    The structural properties of a class of relaxor ferroelectric polymer, poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) [P(VDF-TrFE-CFE)] terpolymer, were investigated and compared with those of the poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] copolymer, the electron-irradiated copolymer, and the chlorotrifluoroethylene (CTFE) based terpolymer. The experimental results suggest that the random incorporation of the bulky chlorofluoroethylene (CFE) monomer into the polymer chain introduces random defect fields, thus randomizing the inter- and intra-chain polar coupling and breaking the large polar domains into smaller domain sizes. Furthermore, CFE also favors intra-chain trans-gauche conformation. As a result, high electrostrictive strain (>5%) was obtained for the terpolymer with a small mol% of CFE.
