Thermally stimulated discharge currents in cellulose acetate films

Abstract

Abstract Thermally stimulated discharge current measurements were made with cellulose acetate films at different polarizing fields and temperatures. While two peaks were obtained, in general, for specimens polarized at low fields and temperatures, only one peak was observed for higher fields and temperatures. The activation energies were evaluated. The origin of the TSDC is attributed to the homotype space charge polarization and trapping of electrons injected from the electrodes with some contribution from dipolar orientation.
