In this paper we present an experimental study of the electron transport in composite samples based on an insulating matrix of polybenzimidazole with graphite nanoparticles as conducting filler. Based on a qualitative analysis of the temperature dependences of electrical resistance obtained for the samples with different filler concentrations, it was established that the electron transport occurred mostly by tunneling between conducting filler particles, with variable-range hopping conduction taking place at low temperatures.

聚苯并咪唑基体与石墨纳米粒子复合材料中的电子输运机理

在本文中,我们基于聚苯并咪唑的绝缘基质和石墨纳米颗粒作为导电填料,对复合样品中电子传输进行了实验研究。基于对不同填料浓度样品获得的电阻的温度依赖性的定性分析,可以确定电子传输主要是通过导电填料颗粒之间的隧穿发生的,而变程跳变导电则发生在低温下。
