Enhancement of pyroelectricity in a vinylidene fluoride−tetrafluoroethylene copolymer

Abstract
Pyroelectric coefficients of a copolymer of vinylidene fluoride (95%) and tetrafluoroethylene (5%) have been measured, and were found to be significantly higher than those obtained for the poly(vinylidene fluoride) homopolymer. The effect of poling time and the nature of the (first cycle) thermally stimulated currents are also compared.
