Frequency dependence of pyroelectric current in poly(vinylidene fluoride) heat sinked at various temperatures

Abstract
The frequency and temperature dependences of pyroelectric activity in poly(vinylidene fluoride) have been studied from 10 to 369 °K using mechanically chopped and steady-state radiation. From these data, thermal diffusivity and a parameter indicating the polarization inhomogeneity can be deduced and compared with a mathematical model.
