摘　　要：采用原位聚合法制备了芳纶/聚苯胺(PPTA/PANI)复合导电纤维,探讨了氧化剂种类与质量浓度、掺杂剂种类与浓度、苯胺单体浓度、反应时间、反应温度对复合纤维导电性能的影响。结果表明:当采用过硫酸铵为氧化剂,以盐酸和硫酸为掺杂剂时,复合纤维的电导率最高,掺杂剂浓度、苯胺单体含量、反应时间、反应温度等因素影响纤维电导率。以过硫酸铵为氧化剂、盐酸做掺杂剂,当过硫酸铵质量浓度25 g/L、盐酸浓度0.6 mol/L、苯胺单体质量浓度16 g/L、反应时间2 h、反应温度20℃时,能制得具有良好导电性能的复合纤维,纤维的电导率达0.47 s/cm。This paper prepares PPTA/PANI composite conductive fiber using in-situ polymerization method and discusses the influence of the type and mass concentration of oxidant, type and concentration of dopant, aniline monomer concentration, response time and temperature on the conductivity of composite fiber. The result shows that composite fiber has the highest conductivity when ammonium persulfate is used as oxidant and hydrochloric acid and sulfuric acid are used as dopants and that factors such as the concentration of dopant, content of aniline monomer, response time and temperature affect the conductivity of fiber. Composite fiber with a good conductivity can be made, with its conductivity up to 0.47 s/cm, when ammonium persulfate is used as oxidant and hydrochloric acid and sulfuric acid are used as dopants and the mass concentration of ammonium persulfate 25 g/L, concentration of hydrochloric acid 0.6 mol/L, mass concentration of aniline monomer 16 g/L, response time 2 h and response temperature 20 ℃.
