摘要

研究了热塑性聚酰亚胺的导电过程。接收到的样品显示，即使施加了任何极化偏置，电流峰值也在/spl sim/230/spl度/C。然而，如果重复测量，这种自发电流就会消失。样品经过热处理后，传导电流减小。认为残留在样品中的K、Na等杂质是产生电流峰或自发电流的原因。

Electrical properties of thermoplastic polyimide

Conduction process of thermoplastic polyimide has been examined. The as-received sample shows a current with a peak at /spl sim/230/spl deg/C even when any poling bias has been applied. However, this spontaneous current disappears if the measurement is repeated. Conduction current decreases if the sample was heat-treated. It is considered that impurities such as K and Na remaining in the sample are responsible for the current peak or the spontaneous current.
