沥青基碳纤维表面复合处理的研究

Multiple Tratmemt of Pitch Based Carbon Fibers

摘要: 研究了硝权氧化和硝酸－钛酸酯复合对沥青基碳纤维（Ｃ－１２）进行表面处理的影响。利用富里衰转换红外光谱扫描、接触角测定及Ｘ－射触角测定及Ｘ－射线衍射等手段，对表面处理各阶段碳纤维的性能与结构进行表征。复合处理与砂酸氧化的机理与效果不同，红外光谱中有新峰出现，纤维表面极性与浸润性发生了变化，认为复合处理方法将有利于拓宽碳纤维的应用范围。

Abstract: Two modified methods of nitric acid oxiation and nitric titanate multiple treatment were used to treat pitch based carbon fibers. It was concluded that the multiple treatment gave better effects than single treatment and enlarged the applied fields of c
