Although membrane distillation (MD) is a promising technology for water desalination and industrial wastewater treatment, the MD process is not widely applied in the global water industry due to the lack of a suitable membrane for the MD process. The design and appropriate manufacture are the most important factors for MD membrane optimization. The well-designed porous structure, superhydrophobic surface, and pore-wetting prevention of the membrane are vital properties of the MD membrane. Nowadays, electrospinning that is capable of manufacturing membranes with superhydrophobic or omni phobic properties is considered a promising technology. Electrospun nanofibrous membranes (ENMs) possess the characteristics of cylindrical morphology, re-entrant structure, and easy-shaping for a specific purpose, benefiting the membrane design and modification. Based on that, this review investigates the current state and future progress of the superhydrophobic, multi-layer, and omniphobic ENMs manufactured with various structural designs for seawater desalination and wastewater purification. We expect that this paper will provide some recommendations and guidance for further fabrication research and the configuration design of ENMs in the MD process for seawater desalination and wastewater purification.
虽然膜蒸馏（MD）是一种很有前途的海水淡化和工业废水处理技术，但由于缺乏适合 MD 工艺的膜，该工艺在全球水行业并未得到广泛应用。膜的设计和适当的制造是 MD 膜优化的最重要因素。膜的良好设计的多孔结构、超疏水表面和防孔润湿是 MD 膜的重要特性。如今，能够制造具有超疏水或全疏水性的电纺丝被认为是一种很有前途的技术。静电纺纳米纤维膜（ENMs）具有圆柱形态、倒棱结构和易于成型的特点，有利于膜的设计和改性。基于此，本综述研究了具有各种结构设计的超疏水、多层和全疏水性 ENMs 用于海水淡化和废水净化的现状和未来进展。我们希望本文能为进一步的制备研究和 MD 过程中用于海水淡化和废水净化的 ENMs 的结构设计提供一些建议和指导。
