Abstract :
The pyroelectric effects of PVDF and of the 50/50 P(VDF-TrFE) (polyvinylidene fluoride-trifluoroethylene) copolymers have been investigated. A novel experimental method is described which enables the simultaneous measurement of the static and dynamic pyroelectric coefficient on the same sample within one single temperature scan. Static measurements with partially clamped samples showed a significant piezoelectric contribution to the pyroelectric coefficient
