摘要

膜分离技术具备高效、节能的优势，广泛应用于生物、水处理、仿生等领域。然而，选择性分离膜在使用过程中产生的膜污染会导致分离效率显著降低，成本提高。膜污染是指微粒及大分子在膜孔吸附、沉积，使膜通量变小的过程。通过对膜结构及膜表面电荷、亲水性、粗糙度的调控可以有效降低膜污染程度，提高分离膜的处理效率。本文总结了近期膜表面改性方法研究进展，重点介绍了化学接枝、物理涂覆、聚合反应改性以及表面分离的防污改性方法。

Abstract

Membrane separation technique is applied widely in biology

water treatment and biomimetic due to its high efficiency and energy conservation. However

membrane fouling will lead to significant reduction in separation efficiency and higher cost. Due to the adsorption and deposition of microparticles and macromolecules in the membrane pores

which result in the decrease of the membrane flux and consequently in membrane fouling. The separation efficiency can be improved by regulating membrane structure and modifying surface charge

surface hydrophilicity

surface roughness and surface biomimetic adhesion of the membrane. In this minireview

membrane surface modification methods were summarized

including coating

grafting and surface segregation methods

along with modification through polymerization process.
