Demonstration of a pyroelectric conversion power cycle with a polymer. Final report, October 1983-October 1984

Technical Report ·
OSTI ID:6307020
Copolymers of vinylidene fluoride trifluoroethylene P(VDF-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 mJ/cc, 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.
