介绍了纳滤膜的作用机理以及纳滤膜的制备方法。其分离机理可以运用电荷模型（空间电荷模型和固定电荷模型），细孔模型以及静电排斥和立体阻碍模型等来描述。随着纳滤膜日益广泛的应用，对其制备方法的研究也得到各研究部门的重视，在本文中我们主要讨论了几种常用的纳滤膜的制备方法。

The separation mechanism and synthesis methods of nano -filtration （NF） membranes were introduced. The separation mechanism of NF membranse can be expressed on the basis of the space - charge model, the fixed - charge model（ i. e. the teorell - meyer - sievers model）, the pore model and the electrostatic and steric - hindrance model. With the widely used of NF membranes, the methods of preparing it were attracted more attention by many research depart- ments. Several methods commonly used were mainly discussed.
