Thermally stimulated discharge current (TSDC) in foils of
polyvinylidene fluoride (PVDF) was measured under various polarizing
conditions. The TSDC thermograms were recorded by reheating the samples at a
linear rate of 3 oC/min. It was found that samples give rise to a peak
around (100 ± 10 oC). The peak position is not consistent with the
polarization fields and temperatures. The activation energy associated with the
peak is found to be ~ 0.62 eV. The dependence of TSD current and TSDC data on
polarizing agents, i.e. field and temperature is explained on the basis of
theoretical predictions. The space charge polarization contributes
significantly to the polarization of the polymer.
