基于静电纺丝技术制备超滤膜的研究进展

摘要

归纳了基于静电纺丝技术制备的超滤膜的原材料,包括聚丙烯腈超滤膜(PAN)、聚砜类超滤膜(PS)、醋酸纤维素超滤膜(CA)；介绍了超滤膜的过滤机理和结构；同时阐述了评价超滤性能的两个主要评价指标(即纯水通量、截留率)以及超滤膜在膜污染方面的改善研究.%The raw materials of the ultrafiltration membrane based on electrospinning technology are summarized, including polyacrylonitrile (PAN) , polysulfone (PS) , cellulose acetate (CA). The mechanism and special composite structure of the ultrafiltration membrane are introduced. At the same time, the two major evaluation indices of filtration-pure water flux and rejection, and the improvement of membrane fouling are also illustrated.
