摘要:

高分子分离膜已广泛应用于水处理、食品、生物医药等领域。 然而,常用的膜材料如聚醚砜(PES)、聚砜(PSf)、聚偏氟乙烯(PVDF)等容易吸附蛋白质和微生物形成膜污染,进而影响膜的性能和使用寿命。 膜污染尤其是膜的生物污染成为限制膜广泛应用的主要瓶颈之一。 本文从亲水改性、抗菌改性及亲水抗菌双功能改性三方面综述了控制膜污染的研究进展和现状,并对其未来发展方向进行了展望。

关键词: 分离膜, 表面改性, 抗菌, 抗污染

Abstract:

Polymeric membrane is widely used in various separation processes such as in wastewater treatment, food and dairy processing, biological medicine, and so on. However, most of the materials used to fabricate separation membrane such as polyethersulfone(PES), polysulfone(PSf), poly(vinylidene fluoride)(PVDF) are easy to be fouled by proteins and microbes. As time goes on, the membrane surfaces are fouled by proteins and microbes will form biofilm which decreases the membrane performance and lifetime. Membrane fouling, especially biofouling, is one of the major obstacles for widespread implementation of membrane. The progress in inhibiting the biofouling of membranes is introduced briefly, including hydrophilic modification, antibacterial modification and integrated hydrophilic and antibacterial modification. This review will provide an important insight for the new antibacterial and antifouling membrane development and potential utilization.

Key words: separation membrane, surface modification, antibacterial, antifouling
