Research Progress in Preparation and Modification of PVDF Microporous Membrane via Thermally Induced Phase Separation
【摘要】 本文综述了采用热致相分离(Thermally induced phase separation,TIPS)法制备聚偏氟乙烯(Polyvinylidene fluoride,PVDF)微孔膜的研究进展。从TIPS法制备PVDF微孔膜的成膜机理出发,阐述了单一稀释剂、复合稀释剂和不同改性方法对PVDF微孔膜结构与性能的影响,并介绍了TIPS法所制备PVDF微孔膜的在水处理工程中的应用情况。
【Abstract】 In this paper, the research progress of polyvinylidene fluoride(PVDF) microporous membranes prepared via thermally induced phase separation(TIPS) method was reviewed. The membrane forming mechanisms were summarized and the influences of single diluent, composite diluent and different modification methods on the structure and properties of PVDF microporous membrane were discussed based on these mechanisms. Finally, the applications of the TIPS-PVDF microporous membrane in water treat projects were also introduced.
