将合成的导电聚（3，4-乙撑二氧噻吩）一聚对苯乙烯磺酸（PEDOT—PSS）与聚乙烯醇（PVA）共混，通过湿法纺丝，得到了电导率较高、力学性能良好、可进行机织的PEDOT-PSS／PVA复合导电纤维，研究了牵伸倍率对纤维导电性能、结构、热性能和力学性能的影响。结果表明：随着牵伸倍率的增加，PEDOT—PSS／PVA复合导电纤维表面的微纤数量增加，结晶性能、热稳定性及力学性能均有所提高；当PEDOT-Pss／PVA复合导电纤维的牵伸倍率为4．0时，其断裂强度、伸长率和初始模量分别为6．74cN／dtex、5．95％和42．43cN／dtex，电导率可达到34．5S／cm，具有良好的应用性能。
Composite conductive fibers with high conductivity, good mechanical properties and well- behaved spinnability were obtained by the wet spinning based on poly（3,4 - ethylenedioxythiophene）- polystyrene sulfonic acid （PEDOT- PSS） blended with polyvinyl alcohol（PVA）. The effect of draw ratios on the conductivity, structure, thermostability and mechanical properties of the fibers was investigated. The results show that the number of microfibers on the surface of PEDOT- PSS/PVA composite fiber increases, and its crystallization, thermal stability and mechanical properties are all improved with the increase of the draw ratio. When the draw ratio of PEDOT -PSS/PVA composite fiber is 4.0, its breaking strength, tensile stretch and initial modulus are 6.74 cN/ dtex, 5.95 %and 42.43 cN/dtex, respectively, and its conductivity reaches 34.5 S/cm, which presents a good utility.
