摘　　要：为了开发超吸水纤维非织造材料,以丙烯酸(AA)-丙烯酰胺(AM)的共聚物为纺丝液经静电纺丝工艺制备纤维毡。通过添加不同浓度的戊二醛(GA)作为交联剂进行静电纺丝制备出一组吸水倍率不同的纤维毡。利用电子显微镜、傅里叶变换红外光谱分析仪对其纤维的形态、官能团种类进行分析,分别测试对于去离子水和生理盐水的吸水性能,计算吸水倍率。实验表明,当GA浓度为1.0%时制得的纤维毡表面形貌最好;红外分析说明发生共聚和交联反应生成=C-H、-CONI!?以及-C=0;将超吸水纤维毡分别在去离子水和0.9%的生理盐水中进行吸水测试,GA的浓度应为1.0%,此时溶液交联度最好,纤维毡吸水性能也最佳,适宜用作超吸水材料。In order to develop a superabsorbent fiber nonwoven material,a copolymer of acrylic acid(AA)-acrylamide(AM)was prepared as a spinning solution to prepare a fiber mat by an electrospinning process.Electrospinning was carried out by adding different concentrations of glutaraldehyde(GA)as a crosslinking agent to prepare a group of fiber mats with different water absorption ratios.The morphology and functional groups of the fibers were analyzed by electron microscope and Fourier transform infrared spectroscopy analyzer,the water absorption properties of deionized water and physiological saline were tested separately,and the water absorption ratios were calculated.Experiments showed that the resulting fiber mat had the best surface morphology when GA concentration was 1.0%.The infrared analysis indicated that copolymerization and cross-linking reactions generated=C-H,-CONH2,and-C=0.The superabsorbent fiber mat was tested for water absorption in deionized water and 0.9%physiological saline respectively.The concentration of GA should be 1.0%,the crosslinking degree of the solution was best,and the fiber mat had the best water absorption performance,which was suitable as a superabsorbent material.
