This paper presents an overview on recent developments in surface modification of polymer membranes for reduction of their fouling with biocolloids and organic colloids in pressure driven membrane processes. First, colloidal interactions such as London-van der Waals, electrical, hydration, hydrophobic, steric forces and membrane surface properties such as hydrophilicity, charge and surface roughness, which affect membrane fouling, have been discussed and the main goals of the membrane surface modification for fouling reduction have been outlined. Thereafter the recent studies on reduction of (bio)colloidal of polymer membranes using ultraviolet/redox initiated surface grafting, physical coating/adsorption of a protective layer on the membrane surface, chemical reactions or surface modification of polymer membranes with nanoparticles as well as using of advanced atomic force microscopy to characterize (bio)colloidal fouling have been critically summarized.
本文综述了近年来用于减少压力驱动膜过程中生物胶体和有机胶体污染的聚合物膜表面改性的最新进展。首先，讨论了影响膜污染的胶体相互作用，如伦敦-范德华力、电、水合、疏水力、空间位阻力以及膜表面性质，如亲水性、电荷和表面粗糙度，并概述了膜表面改性以减少污染的主要目标。此后，本文还对使用紫外/氧化还原引发的表面接枝、在膜表面物理涂覆/吸附保护层、用纳米粒子对聚合物膜进行化学反应或表面改性以及使用先进的原子力显微镜来表征（生物）胶体污染的研究进行了批判性总结。
