摘要:
本文以课题组通过热致相分离法(TIPS)制备聚偏氟乙烯(PVDF)超微滤膜及其产业化的相关工作为基础,从PVDF材料性能及其超微滤膜制备方法出发,全面回顾了课题组在TIPS法PVDF膜制备方面的研究历程,包括稀释剂和非溶剂的探索,纳米粒子、共聚物、两性离子等对PVDF膜的改性研究以及PVDF中空纤维膜组件的研制和规模化生产等等,最后还简要介绍了膜组件在不同工业领域的应用情况。
Preparation and application of polyvinylidene fluoride (PVDF) membranes via thermally induced phase separation (TIPS) method were reviewed on the basis of our work. To begin with, PVDF property and the preparation techniques of its microfiltration/ ultrafiltration (MF/UF) membranes were introduced. Then our research results on the preparation of PVDF membranes via TIPS method was comprehensively reviewed, including the selections of diluents and non-solvents, the effects of nanoparticles, hydrophilic polymer and zwitterionic polymer on the PVDF membrane properties, as well as the fabrication and production of the PVDF hollow-fiber membranes. In the end, the applications of the PVDF hollow-fiber membrane modules in some industrial fields were presented.
