A novel antifouling and antibacterial surface-functionalized PVDF ultrafiltration membrane via binding Ag/SiO2 nanocomposites

摘要

BACKGROUND: Membrane fouling is a main obstacle hindering wider application of membrane technologies, and can cause a decline in flux and increased energy consumption, and more frequent chemical or membrane replacement can increase the operating costs. Membrane fouling is mainly governed by organic fouling and biofouling. In recent years, the development of new materials has provided new methods and thoughts for the research and development of antifouling and antibacterial membranes.
