超滤膜的改性研究及应用

随着超滤膜技术的发展，人们对超滤膜提出了各种各样的特性要求，其中解决膜表面的污染问题变得越来越紧迫．超滤膜改性，尤其是在膜表面引入亲水性基团是解决问题的关键．本文从这点出发，结合自身的工作，总结了近年高分子超滤膜改性方面的研究进展，包括表面活性剂在膜表面的吸附改性、等离子体改性、辐照改性、高分子合金和表面化学反应等几种改性方法．

Surface modification of ultrafiltration membrane and its application

With the development of membrane technology,people have a variety of requirements for UF membranes,one of them is to solve the fouling problem on the membrane surface.Surface modification,especially,to introduce hydrophilic groups onto the surface of the membrane is an effective way.This article reviews the progress in this field,including the methods such as surfactant adsorption on membrane surface,plasma treatment,radiation modification,polymer alloy and sruface reaction etc.
