摘　　要：以可紫外光固化的氟碳树脂(FEVE)-丙烯酸酯共聚物(FEVEA)为原料,通过溶液静电纺丝(电纺)法制备了FEVEA超细纤维。通过扫描电镜(SEM)分析,研究了聚合物溶液质量分数、溶剂配比、电压、接收距离、聚合物溶液流速对电纺纤维形貌及其平均直径的影响,找到了电纺的最佳工艺参数。在混合溶液质量分数为45%,混合溶剂甲苯与乙酸乙酯质量比为2∶3,电压为18 k V,接受距离为20 cm,喷丝头内径为0.24 mm,溶液进料速度为3m L/h的最佳纺丝条件下,可以制得平均直径为2.43μm的FEVEA电纺纤维。With ultraviolet-curable fluoro ethylene-alkyl vinyl ether/ester alternative copolymer （FEVE） -acrylate copolymer （FEVEA） as raw material, FEVEA uhrafine fiber was prepared by electrospinning. The effects of polymer concentration, solvents ratio, applied voltage, tip-collector distance, polymer solution flow rate on the morphology and average diameter of the electrospun fiber were investigated by scanning electron microscopy, so the optimal electro spinning process parameters were determined. Electrospun FEVEA fibers with an average diameter of 2.43 I^m were prepared under the following optimal process parameters： the mass fraction of FEVEA solution was 45%, the mass ratio of toluene to ethyl acetate in the mixed solvent was 2 ： 3, the applied voltage was 18 kV, the tip-collector distance was 20 cm, the inner diameter of the needle was 0. 24 mm, and the polymer solution flow rate was 3.0 mL/h.
