Abstract:

Solvent-resistant nanofiltration is a new type of membrane separation technology used for the separation of organic mixtures. Commercial solvent-resistant nanofiltration membranes are mostly asymmetric membranes with integral skin layers prepared by phase inversion, with thicker skin layers and low flux. The solvent-resistant composite nanofiltration membrane is composed of a support membrane and a separation layer, and has the advantages of thin skin layer, high solvent flux and high solute rejection rate, so it is widely used in the field of solvent-resistant nanofiltration. Therefore, the preparation and modification of solvent-resistant composite nanofiltration membranes have become research hotspots in recent years. In this paper, the research progress of solvent-resistant nanofiltration membranes are firstly introduced from six aspects including interfacial polymerization, surface coating, layer-by-layer self-assembly, in situ growth, organic-inorganic hybridization and surface modification. And then, we propose the development prospects of solvent-resistant composite nanofiltration membranes.

Key words: solvent-resistant nanofiltration, membrane, interfacial polymerization, surface coating, layer-by-layer self-assembly, in situ growth, organic-inorganic hybridization, surface modification

摘要:

耐溶剂纳滤是一种新型的膜分离技术,用于有机混合物的分离。商品耐溶剂纳滤膜大多是采用相转化法制备的整体皮层非对称膜,膜皮层较厚,通量较低。耐溶剂复合纳滤膜由基膜和分离层组成,具有薄皮层、高溶剂通量和高溶质截留率的优点。耐溶剂复合纳滤膜的制备与改性也因此成为近年来的研究热点。本文从界面聚合、表面涂覆、层层自组装、原位生长、有机-无机杂化和表面改性六个方面介绍耐溶剂复合纳滤膜的研究进展,最后对其发展前景进行展望。
