这篇评论文章描述了制造聚合物纳滤膜的不同方法的研究。主要关注的是通过界面聚合形成的纳滤复合膜。在该空间内，详细涵盖的主题包括复合结构、用于赋予特定特性的单体和聚合反应物以及用于影响反应的添加剂。其他具有商业重要性的方法包括通过相转化和不同的后处理（例如涂层、接枝）来制造纳滤膜，这些方法可以应用于更多孔的支撑物。还讨论的新兴技术包括逐层涂层、水通道蛋白的掺入以及具有高内部孔隙率的玻璃状聚合物的使用。共同主题包括旨在提高性能（通量、截留率、选择性、减少污垢）的研究以及在更具挑战性的进料（极端 pH 值、高温、氯、溶剂）中取得成功的改进。 (C) 2016 Elsevier Ltd. 保留所有权利。
The review article describes research on different methods for manufacturing polymeric NF membranes. The primary focus is on NF composite membranes formed by interfacial polymerization. Within that space, topics covered in detail include the composite structure, monomeric and polymeric reactants employed to endow specific characteristics, and additives used to influence the reaction. Other approaches covered that have been commercially important are manufacture of NF membranes by phase inversion and different post-treatments (e.g. coatings, grafting) that may be applied to a more porous support. Emerging technologies also discussed include layer-by-layer coatings, incorporation of aquaporins, and use of glassy polymers with high internal porosity. Common themes include research directed to improved performance (flux, rejection, selectivity, reduced fouling) and modifications that allow for success in more challenging feeds (pH extremes, high temperature, chlorine, solvents).
