The DC conductivity of poly(vinylidene fluoride) films

Abstract

Poly(vinylidene flouride), PVDF, has recently attained commercial importance because, when oriented and poled, it becomes both piezo- and pyroelectric [1]. Yet, when determination of the DC conductivity is required over a temperature range, it is this same pyroelectricity which interferes, virtually precluding the determination of the DC conductivity in this material.
