The rising widespread oil‐impacted wastewater warrants an urgent call for innovative approaches to the handling of oily wastewater. A variety of techniques has been investigated to treat oil‐impacted water, and they are found to be inefficient. Electrospun nanofibers emerge as the viable technique to treat oily wastewater precisely owing to their high specific surface areas and interconnected nanoscale pore structures. In this review, a brief background on the study is provided followed by the environmental pollution by the oily wastewater. Subsequent to that, the polyvinylidene fluoride (PVDF) modification methods are also presented followed by the physicochemical properties of both the electrospun PVDF blends and the PVDF‐based composites. Furthermore, the performances of the PVDF‐based composites in oil/water separation are described. It is concluded with the future prospects for using PVDF‐based composites for oil/water separation.

用于油/水分离的 PVDF 基静电纺纳米纤维：综述

受石油影响的废水不断增加，迫切需要创新的方法来处理含油废水。人们已经研究了多种技术来处理受石油影响的水，但发现这些技术效率低下。电纺纳米纤维由于其高比表面积和互连的纳米级孔隙结构而成为精确处理含油废水的可行技术。在这篇综述中，简要介绍了该研究的背景，然后介绍了含油废水对环境的污染。随后，还介绍了聚偏二氟乙烯 (PVDF) 改性方法，以及电纺 PVDF 共混物和 PVDF 基复合材料的物理化学性能。此外，还描述了 PVDF 基复合材料在油/水分离中的性能。最后总结了使用 PVDF 基复合材料进行油/水分离的未来前景。
