摘　　要：开发具有高导电率的功能化纤维能够拓展纤维制品的应用范围。探讨了利用导电高分子材料PPy对SF/PBT纤维改性来制备PPy/SF/PBT复合导电纤维,并分析了不同处理温度对导电纤维表面形貌、增重率、电导率以及力学性能的影响。试验结果表明:处理温度会影响纤维导电层PPy的生成;随着温度的降低,PPy的生成量增加,-18℃处理温度下纤维表面形成了一层均匀且呈片状结构的PPy,增重率为12.1%,纤维的电导率达到1.02×10-2 S/cm,力学性能几乎不受影响。The development of functional fibers with high electrical conductivity can expand the range of applications for fiber products.PPy/SF/PBT composite conductive fibers are prepared by modifying SF/PBT fibers with conductive polymer material PPy.The effect of different processing temperature on the surface morphology,weight gain,conductivity and mechanical properties of conductive fibers is analyzed.The results indicate that the processing temperature affects the formation of PPy in the conductive layer of the fiber.With the decrease of the temperature,the content of PPy on the surface of the composite fibers increases gradually.PPy can be formed at-18℃with an uniform layer.The weight gain rate of the fiber is 12.1%,and the electrical conductivity of the fiber is 1.02×10-2S/cm.The conductive treatment has little effect on the mechanical properties of the yarn.
