化学掺杂及离子注入对聚对苯撑电导性能的影响

The Influence of Chemical Doping and ion Implantation on Electric Conductivity of Polyparaphenylene

采用AlCl3－CuCl2催化体系合成了聚对苯撑（PPP），用离子注入法及化学方法对策对苯撑进行了掺杂，研究了N+离子注入的剂量、能量、温度以及Fecl3掺杂的浓度、温度、时间对聚对苯撑表面电导的影响。结果表明，离子注入掺杂可使PPP表面电导提高4～5个数量级。

Polyparophenylene (PPP) is prepared by AlCl3-CuCl2 catalysts with benzene as the monomer and is doped by chemical methodand N + ion implantstion. The influences Of the concentrstion, temperature and time of chemical doping and the dose, energy and temperature of ion implantation, on PPP conductivity are investigated. The results showed that the conductivity of PPP could be improved with 5 orders of magnitude by ion implantation and the conductivity of PPP could reach about 0. 1Ω - 1 cm-1 by chemical doping. The comparison Of the stability of the material conductive behavior by using the tWo doping methods is presented. It shows that ion implantation is better than chemical doping in stabilizing the electric conductive behavior for the material.
