Abstract
The nature of dynamic pyroelectric responses, superimposed on the time-dependent discharge current of weakly poled polyvinylidene fluoride has been studied in the temperature range −55 to −10 °C. The results show that the observed pyroelectricity is of dipolar origin, occurring in the amorphous phase of the polymer.
