聚丙烯腈纤维结构缺陷的形成和控制

The Formation of Structural Defects in PAN Fibers and Controlling Approaches

为了获得高性能的碳纤维和高质量的碳纤维前驱体原丝,借助于扫描电镜(SEM)和透射电镜(TEM)对原丝和碳纤维的结构缺陷进行观察,并对结构缺陷的形成原因进行分析,提出了控制缺陷的方法,希望为制备高性能的碳纤维提供理论根据。

To obtain high performance carbon fibers and its precursors,based on observation of structural defects of precursor and carbon fibers with SEM and TEM,this paper analyzed the causes of these structural defects,and put forward the controlling approaches,in hopes of providing theoretical basis for preparation of high performance carbon fibers.
