聚偏氟乙烯膜亲水改性研究进展
Research progress of hydrophilic modification of polyvinylidene fluoride membranes
摘要
Abstract
Polyvinylidene fluoride(PVDF),due to its excellent mechanical and chemical properties,has been widely used to prepare microfiltration,ultrafiltration,nanofiltration and reverse osmosis membranes for water treatment. However,its strong hydrophobicity makes it easy get fouled and poor permeability in the water treating process,so it is beneficial to improve the hydrophilic properties by modification. This paper summarized the researches of PVDF hydrophilic modification in recent years from the aspects of blending,co-polymerization,surface grafting and surface coating. By comparing the influence of hydrophilicity,permeability and anti-fouling among various modification methods,we introduced the modification effect and the advantages and disadvantages of various methods. Finally,the trends of PVDF hydrophilic modification research and its industrialization were prospected.关键词
