Abstract: The characteristics and applications of nanofiltration membranes are briefly introduced. Common organic polymer nanofiltration membrane materials are reviewed，including cellulose acetate and aromatic polyamide，novel nanofiltration membrane materials covering natural polymer and polyelectrolyte，inorganic nanofiltration materials and inorganic-organic hybrid composite nanofiltration membrane materials. For these membrane materials，structural characteristics，chemical properties，membrane fabrication processes and applications are contrastingly analyzed and summarized from different perspectives，including high flux，resistance to pollution，organic solvent resistance and chlorine resistance. Then development trends and application prospects of nanofiltration membrane materials are predicted. And in the immediate future，two issues will become hot topics of research. One is the development and structure control of high-performance nanofiltration membrane materials；the other is the design of structure and function with different nanofiltration membrane materials matrixes.

Key words: nanofiltration, membranes, polymers, nanomaterials, nanofiltration, membranes, polymers, nanomaterials
