采用对甲基苯磺酸和磺基水杨酸作掺杂剂，对聚苯胺自支撑膜进行了掺杂研究，考查了掺杂时间、温度以及掺杂溶液浓度对其导电性的影响，并用红外光谱及显色反应对掺杂产物进行了表征。结果表明，掺杂温度对聚苯胺膜电导率的影响较大，通过控制温度，可以制备出电导率达盐酸掺杂水平的导电膜，即～１０３Ｓ·ｍ－１，且具有良好的环境稳定性，在空气中放置一年，其电导率基本保持不变。 Using p-toluenesulfonic acid and sulfosalicylic acid as dopants, the polyaniline self-supporting films were doped, and the effect of doping time, temperature and concentration of doping solution on their conductivity was investigated. Infrared spectroscopy and color reaction of doped products were characterized. The results show that the doping temperature has a great influence on the conductivity of the polyaniline film. By controlling the temperature, the doping level of the conductive film with the conductivity of ~ 103S · m-1 can be prepared and has good environmental stability , Placed in the air for a year, its conductivity remained essentially unchanged.
