低电阻率聚吡咯的合成研究

The optimization of polypyrrole synthesis process conditions and the study of resistance property

分别以氯化铁(FeCl_3)和过硫酸铵(APS)为氧化剂、以十二烷基苯磺酸钠、十二烷基硫酸钠、十二烷基磺酸钠、对甲苯磺酸钠为掺杂剂,采用化学氧化的方法制备得到聚吡咯(PPy)颗粒。以PPy电阻率为评价指标,优化确定化学氧化合成低电阻率PPy的最佳方案,电阻率为0.043/Ω·cm,电阻率较低。

Use FeCl3 and ammonium persulfate（APS）as oxidant,dodecyl benzene sulfonic acid sodium,sodium dodecyl sulfate,sodium dodecyl sulfate,p-toluene sulfonic acid sodium as the doping agent,respectively,by chemical oxidation to obtain polypyrrole particles.Use polypyrrole resistivity as evaluation index,to determine the best solution of chemical oxidation synthesis of lower resistivity of polypyrrole.
