摘要：

In an effort to find higher electrical properties of CNT-based polymer composites, a segregated CNT (carbon nanotube) network model is constructed, and a computational scheme is also provided. The construction involves randomly oriented CNTs decorated on the surface of polymer particles. A two-scale computational scheme with segregated CNT networks as the small scale and the overall composite consisting of polymer particles and segregated networks as the large scale is proposed. The small-scale problem involves percolation feature and is solved...
