Thermally Stimulated Currents in Mylar, High-Temperature Low-Field Case

Abstract
The thermally stimulated current method has been applied to the study of thermally activated depolarization of Mylar thermoelectrets. The band arising from the depolarization is broad and sometimes multistructured. It is, in general, centered at approximately 400°K. The peak current is linear with the applied electric polarizing field up to at least 240 kV cm−1. The linearity is taken as evidence that the polarization is due to dipole orientation.
