摘　　要：以N,N＇-二甲基甲酰胺/四氢呋喃（DMF/THF）混合液为溶剂,基于铝箔的支撑,采用静电纺丝法制备了聚（偏氟乙烯-三氟乙烯）（P（VDF-Tr FE））纤维膜。研究了混合溶剂质量比对纤维形貌、晶相结构和结晶度的影响。结果表明：当溶剂质量比（m（DMF）：m（THF））由8：2变化至5：5时,纤维的形貌发生显著改变,圆形的珠丝逐渐被拉长变成梭形,最终形成直径均匀的纤维,且结晶度由67.1%增至71.0%,但对所制纤维膜的晶型影响较小,其晶型均为极性β晶。The vinylidene fluoride/trifluoroethylene copolymer（P（VDF-Tr FE）） fiber membranes were successfully prepared by electro-spinning based on the support of aluminium foil with mixed solvents of N,N＇-dimethylformamide（DMF） and tetradytrofuran（THF）. The influences of solvent ratio on structure and performance of the resultant membranes were investigated and continuous β phase fibers were obtained. The results show that the morphology of the bead on the fiber changes shape from a rounded droplet-like shape to stretched droplet or ellipse to smooth fiber as the ratios of solvent（m（DMF）：m（THF）） changes from 8：2 to 5：5. Additionally, the crystallinity of the membrane also increases from 67.1% to 71.0%.
