二次掺杂聚苯胺的PAN复合纤维抗静电性能研究

摘要

A polyacrylonitrile (PAN)/polyaniline (PANI) composite fiber was prepared by the graft polymerization of aniline and PAN fiber prior to the first doping with sulfosalicylic acid(SSA). And the obtained composite fiber was secondly doped with hydrochloric acid(HCl). The second doping conditions and the antistatic property of the PAN/PANI composite fiber were studied. The results showed that PANI existed in PAN/PANI composite fiber; the specific resistance of PAN/PANI composite fiber was about 2 1kΩ · cm when the second doping conditions were optimized as followed; HC1 concentration 2 mol/L, reaction temperature 0℃ and time 6 h; and the composite fiber secondly doped with HC1 was superior to the fiber firstly doped with SSA in the antistatic property.%将苯胺与聚丙烯腈(PAN)纤维接枝聚合,第一次采用5-磺基水杨酸(SSA)掺杂制得PAN/聚苯胺(PANI)复合纤维,再以盐酸(HCl)第二次掺杂制得PAN/PANI复合纤维；研究了第二次掺杂的反应条件及PAN/PANI复合纤维的抗静电性能.结果表明:红外光谱分析证明了PAN/PANI复合纤维中有PANI存在；HCl第二次掺杂最佳条件为HCl浓度2mol/L,反应温度0℃,反应时间6h,PAN/PANI复合纤维的比电阻约2 kΩ·cm；第二次用HC1掺杂的复合纤维的抗静电性能比第一次用SSA掺杂的抗静电性能更好.
