摘要

测定了非晶态及双轴拉伸聚对苯二甲酸乙二醇酯（PET）热驻极经γ辐照后热释电（TSC）谱图；观察了空间电荷峰变化规律。探索了PET陷阱本质及陷阱载流子的重组现象。鉴别出非晶态PET中主要载流子类型属空穴型。

Abstract

The Thermally Stimulated Current (TSC) spectra of biaxial stretched polyethylene terephthalate (PET) electret were measue measured, which a had been irradiation by ,γ, rays at dose rate 1×10,4,Gy/h. The space charge peak's value and peak temperature are dramatically decreased with doses below 1×10,3,Gy and then tend to a certain value respectively. The mechanism of decreasing the trap depth has been investigated by means of the comparing with TSC spectra of amorphous PET electret. It has been confirmed that the main species of charge carriers of amorphous PET are the holes.
