Abstract: 1. Thermally stimulated currents (TSC) from polyethylene terephthalate (PET) electrets formed by high electric fields were investigated. Electrons injected from the Al cathode greatly contribute to the TSC above -40℃, the TSC below -40℃ for Al electrodes and at all temperatures for Au electrodes are mainly induced by the depolarization of dipoles. 2. Carrier traps in PET, PEN, PE, PP and PVDF were investigated by TSC and TL analysis in the temperature range from -196 to 100℃. The electron beem with energy of 2∿5 keV irradiated specimens to form electrets at -196℃. It was proved that the electron beem technique was useful for the investigation of carrier traps in vinyl polymers with no π electron groups. 3. Electronic carrier traps in PET and PEN were investigated by photoexcitation techniques. A broad peak was observed in temperature range from -160 to 50℃ in PET photoelectrets illuminated at 300 nm at -180℃. Their apparent trap depth was found to distribute from 0.2 to 0.5 eV. On the other hand, two broad peaks were observed in the TSC and TL from PEN photoelectrets illuminated at 360 nm. Their apparent trap depths ranged from 0.1 to 0.5 eV.
