【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. 更多还原
