Research progress of environmental stimulus responsive nanofiltration membrane

环境刺激响应型膜结合了传统膜材料和智能材料的优势,膜表面的物理化学结构可随外界环境(pH、温度、光、电场等)的变化而改变,从而达到自主调节渗透分离性能的目的,扩大了传统分离膜的应用范围.环境刺激响应型纳滤膜由于其独特的孔结构在小分子物质分离方面具有重要的意义,逐渐受到人们重视.本文简述了环境刺激响应型纳滤膜的最新研究进展,包括环境刺激响应型纳滤膜的制备方法、类型及其在相关领域中的应用现状,并对未来的发展方向进行了展望.

Environmental stimulation responsive(ESR)membrane combines the advantages of traditional membrane materials and intelligent materials,and can change its physicochemical structure in response to the changes of external environment(pH,temperature,light,electric field,etc.),so as to achieve the goal of self-regulation of permeability separation performance and expand the application scope of traditional separation membrane.The ESR nanofiltration membrane has attracted more and more attention due to its unique pore structure,which is of great significance in the separation of small molecular substances.In this paper,the latest research progress of ESR nanofiltration membrane was reviewed,including the preparation methods,type,and its application status in related fields,and the future development direction was also prospected.
