Freshwater deficiency has become a significant issue affecting many nations' social and economic development because of the fast-growing demand for water resources. Nanofiltration (NF) is one of the promising technologies for water reclamation application, particularly in desalination, water, and wastewater treatment fields. Nevertheless, membrane fouling remains a significant concern since it can reduce the NF membrane performance and increase operating expenses. Consequently, numerous studies have focused on improving the NF membrane's resistance to fouling. This review highlights the recent progress in NF modification strategies using three types of antifouling modifiers, i.e., nanoparticles, polymers, and composite polymer/nanoparticles. The correlation between antifouling performance and membrane properties such as hydrophilicity, surface chemistry, surface charge, and morphology are discussed. The challenges and perspectives regarding antifouling modifiers and modification strategies conclude this review.
由于对水资源的需求快速增长，淡水短缺已成为影响许多国家社会和经济发展的一个重大问题。纳滤（NF）是用于水回收应用的有前景的技术之一，特别是在海水淡化、水和废水处理领域。然而，膜污染仍然是一个重大问题，因为它会降低纳滤膜的性能并增加运营成本。因此，许多研究都集中在提高纳滤膜的抗污染能力上。本综述重点介绍了使用三种类型的抗污染改性剂（即纳米颗粒、聚合物以及复合聚合物/纳米颗粒）进行纳滤改性策略的最新进展。讨论了抗污染性能与膜性能（如亲水性、表面化学、表面电荷和形态）之间的相关性。关于抗污染改性剂和改性策略的挑战与展望总结了本综述。
