介绍通过化学反应方法，将铜的硫化物引入到聚丙烯腈（ＰＡＮ）的纤维或粉末中，使其具有良好导电性。通过电阻与温度的变化关系、Ｖ－Ｉ特性以及ＳＥＭ、ＸＰＳ、Ｘ射线等对导电ＰＡＮ的微结构和导电机理进行了研究。同时制备了导电ＰＡＮ／ＡＢＳ复合材料，并测定了复合材料的导电性能。 Introduction By the chemical reaction method, copper sulfide is introduced into fibers or powders of polyacrylonitrile (PAN) so that it has good electrical conductivity. The microstructure and conduction mechanism of conductive PAN were studied by the relationship between the resistance and temperature, V-I characteristics, SEM, XPS and X-ray. At the same time, the conductive PAN / ABS composites were prepared and the conductivity of the composites was measured.
