近年来,采用高聚物共混的方法生产多孔吸水性聚丙烯腈纤维受到人们普遍地重视。纤维内部微孔的数量及孔径分布与纤维许多性能有关,例如,吸水性、渗透性及机械性能等等。因此,研究纤维多孔结构与性能的关系也引起了人们的兴趣。对于双组分共混聚丙烯腈纤维,其结构可以分为三个层次:超分子结构、形态结构以及相态结构,然而,对共混聚丙烯腈纤维结构的研究,报道较少,本文对所研制的几种共混吸水性聚丙烯腈纤维作了初步探讨。
In recent years, the production of porous absorbent polyacrylonitrile fiber by the method of polymer blending has drawn people’s attention. The number of micropores inside the fiber and pore size distribution are related to many properties of the fiber, such as water absorption, permeability and mechanical properties. Therefore, the study of the relationship between fiber porous structure and performance has also drawn people’s interest. For the two-component blend of polyacrylonitrile fiber, the structure can be divided into three levels: supramolecular structure, morphological structure and phase structure, however, the study of the hybrid polyacrylonitrile fiber structure, less reported, Developed several kinds of blended absorbent polyacrylonitrile fiber made a preliminary discussion.
