摘要

在聚酰亚胺薄膜中，对数电导率与温度的相互依赖关系出现断裂。这表明聚酰亚胺薄膜的多重跃迁和弛豫都反映在上述关系中。这为我们提供了确定聚合物电导率随温度变化规律的可能性，这对所有在绝缘领域工作的人都很感兴趣，特别是在半刚性链聚合物领域。

High-temperature conductivity of PI films

In polyimide films, there occur breaks in the reciprocal-temperature dependence of the log-electrical conductivities. It indicates that the multiple transitions and relaxations of the polyimide films are reflected in the above mentioned relationship. This presents us the possibility to determine the rule of variations of the electrical conductivities of the polymer with temperatures and is of interest to all working in the insulation field, especially in the semi-rigid chain polymer field.
