Abstract:
The conduct mechanism of the doped polymer is considered. In an asymmetry system composed of high polymer and doping conductive matte, chain or congeries framework will be formed between the conductive particles to improve the conductance characteristic. In this procession, the conductive particles interact to each other. In this paper, we describe the conductance of the doped polymer by Monte Carlo method. The results accord with the experiments quite well. It can be concluded that there is an evident change of doped polymer from nonconductor to metal.
掺杂法提高聚合物电导的机理是考虑导电填充物和高聚物所构成的不均匀体系中, 导电颗粒间会形成链式组织或聚集体组织而提高导电性能, 在此过程中导电颗粒有相互作用.本文是采用蒙特卡洛法对掺杂高分子材料的电导特性作了研究, 研究结果与实验符合较好, 并得出存在剧变特征的所谓绝缘体——金属相变特性的计算结果.
