摘要：

Thermally stimulated current (TSC) characteristics in poly(ethylene terephthalate) (PET) has been investigated in detail in a high temperature region. The results clearly shows that TSC peak appearing at about 400K is due to ionic space-charge polarization associated with the migration of mobile ions within PET over macroscopic distance. Furthermore a very large TSC peak is observed in the temperature region near 460K, but no thermally stimulated surface potential (TSSP) corresponding to the TSC peak is measured in the same temperature region. This is related to the neutralization of the mobile ions at PET-electrode interface. Sublinear current versus voltage characteristics are observed in a high temperature region. TSC and TSSP measurements show that the conduction is also related to the neutralization. © 1979, The Society of Polymer Science, Japan. All rights reserved.
