基于界面聚合技术的复合纳滤膜研究进展

Research Progress of Composite Nanofiltration(NF)Membrane Based on Interfacial Polymerization Technology

在众多纳滤膜制备方法中,界面聚合法凭借其便捷、高效和稳定的技术特征成为了目前纳滤膜制备的主流技术。纳滤膜的渗透性、选择性、抗污染性等性能特征决定着其能否进一步扩大应用领域与应用规模。为此,国内外众多学者围绕界面聚合技术对纳滤膜的优化制备开展了大量研究工作。文中主要从单体类型选择、基膜类型选择、纳米材料在界面聚合技术中的应用以及新型无支撑界面聚合技术4个方面回顾了复合纳滤膜的研究进展,并就未来研究方向提出了建议。

Among the different NF membrane fabrication methods,interfacial polymerization has become the mainstream technology due to its convenient,efficient and stable characteristics.The properties of NF membrane,including permeability,selectivity and anti-fouling ability,determine whether its application field and scale can be further expanded.Therefore,numerous researchers at home and abroad have carried out a lot of research focusing on the optimizing preparation of NF membranes based on interfacial polymerization technology.This paper reviews the latest research progress of high performance composite NF membranes from four aspects,including monomer selection,substrate membrane selection,application of nanomaterials in interfacial polymerization process and novel non-supported interfacial polymerization technology.Furthermore,suggestions for future research are proposed.
