    Abstract

    The effect of high-energy electron irradiation on poly(vinylidene fluoride- trifluoroethylene) (PVDF-TrFE) copolymer is investigated in a broad range of electron doses in light of a recent finding of the relaxor ferroelectric behavior and large electrostriction in the material. It is shown that although irradiation reduces both the crystalline and polar ordering, the two are not directly related to each other. In contrast to differential scanning calorimetry (DSC) and X-ray results which show that the copolymer becomes amorphous for higher irradiation dose, the dielectric data still exhibit relaxation peak which follows the Vogel-Fulcher law, indicating the presence of local polar ordering.
