摘　　要：膜分离技术作为一种广泛应用于水处理领域的实用性技术,具有巨大的发展潜力。本研究针对水净化领域氧化锌纳米结构和纳米纤维材料的应用状况以及潜在挑战存在显著差异的情况进行了深入的研究和分析,成功制备了一种电纺聚偏氟乙烯(PVDF)纳米纤维膜,其具有出色的比表面积、卓越的柔性和化学稳定性等特性。在最佳制备条件下可得到表面长有直径均匀、分布广泛ZnO纳米线的PVDF纳米纤维膜。ZnO/PVDF纳米纤维复合膜在油水分离方面展现出卓越的性能,在轻油/水混合物的分离中,其效率可保持在97.9%以上,水通量为1120 L·m^(-2)·h^(-1);经5次循环后,其分离水的分离效率仍可达96%以上。As a practical technology widely used in the field of water treatment,membrane separation technology has great potential for development.Aiming at the significant differences in the application status and potential challenges of zinc oxide nanostructures and nanofiber materials in the field of water purification,in-depth research and analysis were carried out.An electrospun polyvinylidene fluoride(PVDF)nanofiber membrane was successfully prepared,which had excellent specific surface area,excellent flexibility and chemical stability.Under the optimum preparation conditions,PVDF nanofiber membranes with uniform diameter and wide distribution of ZnO nanowires could be obtained.The ZnO/PVDF nanofiber composite film showed excellent performance in oil-water separation,and its efficiency could be maintained above 97.9%in the separation of light oil/water mixture,and the water flux was 1120 L·m^(-2)·h^(-1).After 5 cycles,the separation efficiency could still reach more than 96%.
