摘要

本文报道了在高压作用下，用热脉冲法测量了带氧化铝过滤器和不带氧化铝过滤器的三元乙丙共聚物(EPDM)的注入电荷和极化。发现从两个电极上都有同电荷注入，且正同电荷多于负同电荷。外加电压对含有填料的试样产生偶极极化。

Charge injection and polarization in ethylene-propylene copolymer (EPDM) probed with the thermal pulse technique

The authors report measurements of injected charge and polarization in ethylene-propylene copolymer (EPDM) with and without alumina filter using the thermal pulse method, following the application of high voltage. It is found that homocharge injection occurs from both electrodes with more positive homocharge than negative homocharge. Dipolar-like polarization was induced by the applied voltage in specimens containing filler.<>
