摘　　要：采用气相掺杂这种新的掺杂方法对低电导率的导电聚苯胺进行再掺杂,气相掺杂30min的聚苯胺的电导率约为未掺杂导电聚苯胺的4倍,并对其结构进行红外表征,探讨了电导率发生变化的内在机理。该法简便易操作,不引入杂质,不污染环境,是一种很有发展前景的新方法。Low conductive polyaniline was redoped by volatile protonic acid by using the new method of gas doping. The conductivity of polyaniline of gas doping for 30min was approximately 4 times of that of without gas doping, the structure of the redoped polyaniline was investigated by FT-IR spectroscopy, and the mechanism of the change of its conductivity was discussed in this paper. This method is very easy and simple, with the advantage of not carrying in any impurities and not polluting environment. So the new technique has wide prospects.
