在这项研究中，我们通过分析和实验研究了碳纳米管（CNT）基聚合物复合材料的电性能。开发了一种分析模型来预测 CNT 基复合材料的电导率。模型中纳入了纳米复合材料的微米/纳米级结构以及碳纳米管之间基质材料产生的电隧道效应。还对 CNT/聚碳酸酯复合材料进行了电导率测量，以确定其电传输特性对纳米管含量的依赖性。将分析预测与实验数据进行比较，预测结果与实测结果之间具有良好的相关性。此外，还研究了宏观尺度上纳米管几何形状对纳米复合材料电性能的影响。
In this research, we investigate both analytically and experimentally the electrical properties of carbon nanotube (CNT)-based polymer composites. An analytical model was developed to predict the electrical conductivity of CNT-based composites. The micro/nanoscale structures of the nanocomposites and the electrical tunneling effect due to the matrix material between CNTs were incorporated within the model. Electrical conductivity measurements were also performed on CNT/polycarbonate composites to identify the dependence of their electrical transport characteristics on the nanotube content. The analytical predictions were compared with the experimental data, and a good correlation was obtained between the predicted and measured results. In addition, the effect of nanotube geometry on the nanocomposite electrical properties at the macroscale was examined.
