摘要: 研究了用一步反应法制备的CuS表面改性的聚丙烯腈导电纤维的微观结构、导电性和温度的变化规律及其导电机理,观察了CuS在纤维表面上的结晶态及晶型变化现象,证实了该导电纤维的以电子导电为主的导电机理。Abstract: In the present papcr the polyacrylonitrile (PAN) fiber surface modified by CuS has been prepared, using one bath chemical reaction method. It's microstructure, temperature dependcnce of surface condustivity and the conduction mechanism have been investiga
