| 摘 要： | 在导电聚合物的研究中，聚苯胺及其衍生物一直是人们相当感兴趣的课题．此类聚合物既可用氧化剂掺杂，也可进行质子酸掺杂，掺杂后其电导率可提高约十个数量级｛1，’］；利用在主链上引入取代基等化学修饰方法，可方便地调节其溶解性、加工性等物理化学性能．已有的研究结果表明，主链的化学修饰往往给聚苯胺的导电性能带来不利影响＊．因此，如何使聚苯胶类导电聚合物保持高的电导率且同时具备优良的物理加工性能使成为此类导电聚合物研究中的一个亟待解决的问题一本文利用鼻子化学EHMO－CO方法对掺杂和取代影响聚苯胺及其衍生物导电性…

| Abstract: | PolyaIilline and its derivatives is one kind of important conductive polymer.In this paper, the active mechanism of substitution and doping on conductivity of polyanilines was studied by means of EHMO-CO method. The result showed that doping and substitution had different active mechhosm on conductivity of polyedlines, doping lowered markedly the exciting energy of carrier, while substitution altered chieIly the band width. |
