【摘要】 本文运用新型双子表面活性剂6,6’-(丁基-1,4-二基双氧)双(3-壬基苯磺酸)(9BA-4-9BA)作为掺杂剂、二氯乙酸(DCA)为溶剂制备得到可溶性掺杂聚苯胺溶液,对9BA-4-9BA掺杂的聚苯胺溶液的纺丝工艺过程进行了探索,探讨了纺丝工艺参数对纤维导电性能的影响,研究发现,随着初生纤维在空气中的放置时间增加,所得纤维的导电率先增加后减小,能谱分析结果表明纤维表面硫含量也相应地先增加后减小,纤维表面和截面的S含量变化规律与纤维表面导电率测量结果具有很好的对应关系。更多还原

【Abstract】 An conducting polyaniline ( PAni) fiber was produced using a novel Gemini surfactant 6,6’- [butane - 1,4 - diylbis( oxy) ]bis( 3 - nonylbenesulfonic-acid) ( 9BA - 4 - 9BA) as dopant and dichloroacetic acid( DCA) as solvent. The influence of spinning parameters on the conductivity of resulted 9BA - 4 - 9BA doped polyaniline fibers was studied. It was found that the conductivity of resulting 9BA - 4 - 9BA doped polyaniline fibers was increased first,then decreased when the standing time of nascent fiber on air increased, which was confirmed by the results of the Elemental Sulfur content on the surface and cross-sections of resulting fibers measured by Energy Dispersive spectrum ( EDS) analysis.更多还原
