Abstract

The authors have observed two peaks in TSC (thermally stimulated current) spectra of Du Pont polyimide film. The low-temperature peak in the range of 50-70°C is ascribed to dipole depolarization of unimidized polyamic acid in the film. The high-temperature peak in the range of 160-180°C, in agreement with the authors' experimental results, is attributed to depolarization of ionic space charge generated by ionization of unimidized polyamic acid, ionic impurities, and water and then bound into Frohlich's two-potential well.
