摘要

近几十年来，人们对合成聚合物中的电击穿过程进行了积极的研究。然而，他们的细节尚未完全了解。最近，作者开发了一种测量预击穿电流的系统，并试图阐明聚合物绝缘体中预击穿电流的击穿机制[1-4]。在之前的论文[2]中，我们发现聚酰亚胺(PI)的预击穿电流在90℃击穿前10−3 s左右开始迅速增加，并从热击穿的角度解释了这一点。

Pre-breakdown currents in polyimide films

The electrical breakdown processes in synthetic polymers have been actively investigated these decades. However, their details have not yet been fully understood. Recently, the authors have developped a system for measuring a pre-breakdown current and tried to clarify the mechanism of a breakdown from pre-breakdown currents in polymeric insulators [1-4]. In the previous paper [2], we found that a pre-breakdown current in polyimide (PI) started to increase rapidly around 10−3 s just before a breakdown at 90 C and explained it in terms of the thermal breakdown.
