【摘要】 以聚丙烯腈纤维为基体,先后进行紫外辐射接枝苯乙烯、碱性水解、氯甲基化及乙二胺胺化反应,制备出机械性能良好,阳离子交换容量为2.19 mmol/g,阴离子交换容量为0.73 mmol/g的两性离子交换纤维.研究了反应过程中各种因素对反应的影响,得出最佳反应条件,并对两性离子交换纤维进行红外光谱和扫描电子显微镜的表征.实验结果表明:PAN纤维制备两性离子交换纤维的方法可行.

【Abstract】 With the polyacrylonitrile fibers as base materials,the amphoteric ion exchange fiber was successfully prepared after the UV graft polymerization copolymerization with styrene,alkaline hydrolysis,chloromethylation and ethylenediamine amination,which cation exchange capacity was 2.19 mmol/g and the anion exchange capacity was 0.73 mmol/g,and the mechanical strength behaves well.Through the exploration of process parameters,the optimum synthesis condition was obtained.Method of IR and SEM were used to characterize the ion exchange fibers and the result showed that the preparation method of amphoteric fibers from PAN fiber in weak acidic/weak basic is feasible.
