【摘要】 采用广角Ｘ－射线扫描、扫描电子显微镜、差示扫描量热法、比电阻测定等方法，对含不同量Ｃｕ＿９Ｓ＿５导电成分的导电性腈纶的结构和性能进行分析。研究表明，含Ｃｕ＿９Ｓ＿５导电性腈纶的高序区大分子间等距离排列的现整性显著降低，而结构单元平行排列状态以及纤维的宏形态结构无明显变化；腈纶中Ｃｕ＿９Ｓ＿５含量在１２．５％以上则具有良好的导电性，具有Ｐ型半导体的导电特征；纤维的物理机械性能无明显劣化，但其热性能受到一定程度的影响。更多还原

【Abstract】 By means of WAXD, SEM,DSC and resistance determination, the structure and properiies of conductive PAN fiber with different content of conductive compound Cu₉S₅ are analysed.The results shows that the molecular normalization in high ordered region decreases distinctly due to the influence of Cu₉S₅, but there is a less change on the oriented structure of the unit and macrostructure of the fiber. When the content of Cu₉S₅ within PAN fiber is up to 12.5%,the fiber has an excellent conductivity and the conductive characteristics of the se- mi-conduct type-P. The conductive PAN fiber keeps a good physical mechanical property, while it’s thermal property is influenced to some extent.更多还原
