The magnitude of the pyroelectric coefficient in polyvinylidene fluoride was observed to increase significantly on maintaining the poling field while cooling the samples from elevated poling temperatures to ambient temperature. The results of the measurement of the depolarization currents with repeated thermal cycling of poled specimens from temperatures well above that of poling conditions to 30 °C suggest that dipolar reorientations may be responsible for the pyroelectricity in PVF2. These observations hold for both the conventional poling and the corona charging of PVF2films, originally containing form 1 and form 2 crystallites.
