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
