摘　　要：将聚乙烯醇(PVA)水溶液与聚3,4-乙撑二氧噻吩∶聚对苯乙烯磺酸根阴离子(PEDOT∶PSS)水分散液共混,在不同的纺丝体系温度下,通过湿法纺丝方法制备出PVA/PEDOT∶PSS共混纤维。在制备出PVA/PEDOT∶PSS共混纤维的基础上,探究了纺丝体系温度对共混纤维化学结构、表面形貌、导电性能及拉伸力学性能的影响。借助扫描电子显微镜、红外光谱分析仪、高阻计和电子单纤维强力仪对共混纤维进行测试表征。结果表明:随着纺丝体系温度的升高,制备出的PVA/PEDOT∶PSS共混纤维的导电性能逐渐升高,电导率由1.55S/cm增加到2.39S/cm;制备出的PVA/PEDOT∶PSS共混纤维表面形貌有一定程度改善,纤维表面沟槽数量减少;制备出的PVA/PEDOT∶PSS共混纤维的拉伸强度逐渐升高,断裂伸长逐渐降低。PVA/PEDOT：PSS blended fibers were successfully prepared by the wet-spinning process of mixed aque- ous solution composed of PVA and PEDOT： PSS at different spinning-system temperature. On the basis of this work, the effects of spinning-system temperature on chemical structure, surface morphology, electrical conductivity and tensile me chanieal property of blended fibers were investigated in detail. Scanning electron microscopy （SEM）, Fourier transform in frared spectroscopy （FT IR）,high resistance meter and single fiber strength tester were employed to test and characterize the blended fibers. The results showed that with the rising of spinning-system temperature,electrical conductivity of blen- ded fibers increased from 1.55S/cm to 2.39S/em. The tiny grooves on the surface of blended fibers decreased, the tensile strength increased while the elongation at break decreased.
