尽管电纺纤维比表面积大,但其力学性能差,且缺少活性基团,这极大地限制了其应用。首先,用甲苯乳液增强处理电纺聚苯乙烯超细纤维膜,然后,用包埋在电纺纤维中的偶氮二异丁腈引发甲基丙烯酰丙基三甲基氯化铵接枝聚合改性,详细研究了混合溶剂比例、交联剂用量对接枝共聚过程的影响。研究结果表明：甲苯乳液可有效地增强电纺纤维膜。水接触角、吸水率、红外光谱和扫描电镜等结果显示,阳离子单体成功接枝到了超细纤维的表面。

Although the electrospun polymer fiber shows large specific surface area, its mechanical strength is usual- ly poor, and the polar groups are often devoid. The electropsun polystyrene fibrous mats were treated with toluene e- mulsion and heated in oven in order to improve their mechanical strength. Afterwards, the polystyrene nonwovens embedded with the initiator azobisisobutyronitrile were further grafted with methacrylamido propyl trimethyl ammonium chloride （MAPTAC） in aqueous solution. The effects of the volume ratio of methanol to water and the dosage of the crosslinking agent N,N＇ -methylene-bis-acrylamide on the grafting were investigated in detail. The toluene emulsion effectively improved the nonwoven tensile strength. The results of water contact angle, water uptake, infrared spectra, and scanning electron microscopy all showed the monomer was successfully grafted onto the fiber surface.
