摘要
研究了几种聚合物材料（ＰＰ，ＰＴＦＥ，ＰＥＴ，ＰＩ）经过γ辐照后，电流－电压特性的变化；从辐照对材料结构的影响，探讨了辐照后材料的电导机理及空间电荷对於辐照后材料电性的影响。
The conductive mechanism of polymers(PP,PTFE,PET,PT)was studied according tothe variation of current-voltage characteristics and their construction before and after irradia-tion,It is found that the space charge has some effect on the electrical properties of the poly-mers after irradiation,and the behaviour of irradiation stability of the polymers can be distin-guished from their conductive variation after irradiation.
