以苯乙烯-丁二烯-苯乙烯（St-B-St）为原料，在甲苯中原位生成过氧甲酸，通过静电纺丝法制备了纳米TiO 2包埋的环氧化苯乙烯-丁二烯-苯乙烯（St-B-St）纳米纤维。得到了制备纳米二氧化钛/环氧化苯乙烯-丁二烯-苯乙烯共混静电纺丝纤维的最佳工艺参数。采用扫描电子显微镜和抗紫外线透过率测试仪，参照美国纺织化学家和染色师协会（AATCC 183 -2004）标准，对纳米二氧化钛/环氧化苯乙烯-丁二烯-苯乙烯复合纤维的形貌和抗紫外线性能进行了研究。扫描电镜结果表明，纳米二氧化钛和环氧基的引入导致了静电纺丝纤维的粘结。金红石型纳米二氧化钛/环氧化苯乙烯-丁二烯-苯乙烯纤维膜的紫外防护因子是四种纤维膜中最大的。纳米二氧化钛包埋的环氧化苯乙烯-丁二烯-苯乙烯纳米纤维在防紫外线纺织品方面具有很大的应用潜力。
The epoxidized styrene–butadiene–styrene nanofibers, which were prepared by epoxidation of the styrene–butadiene–styrene in toluene with peroxyformic acid generated in situ, were successfully embedded with nanometer titania dioxide by electrospinning. The optimum blended electrospinning parameters on preparing the nanometer titania dioxide/epoxidized styrene–butadiene–styrene fibers were obtained. The morphology and antiultraviolet property of nanometer titania dioxide/epoxidized styrene–butadiene–styrene composite fiber were examined using scanning electron microscope and an antiultraviolet transmission tester according to American Association of Textile Chemists and Colorists (AATCC183-2004) standard. The scanning electron microscope results showed that nanometer titania dioxide and the epoxy group could lead to the cementation of electrospinning fibers. The ultraviolet protection factor of rutile nanometer titania dioxide/epoxidized styrene–butadiene–styrene fiber membrane is the largest one of the four fiber membranes. The epoxidized styrene–butadiene–styrene nanofibers embedded with nanometer titania dioxide have great potential in the applications of antiultraviolet textiles.
