Abstract:

Copolymers of vinylidene fluoride trifluoroethylene PVDF-TrFE exhibit large piezoelectric effects. Standard isothermal D-E hysteresis loops were found to be inaccurate predictors of the pyroelectric conversion performance of this material. Conduction effects obscured the observation of conversion cycles for the presently available materials. A conversion cycle was measured with electric energy density of 30 mJcc, which is 15 times larger than that of any other polymer yet measured. Resistivity and displacement change data are discussed in terms of predicted pyroelectric energy conversion performance. Author
