摘要：

热致相分离（Thermally Induced Phase Separation, TIPS）法是相转化法中重要的一种制备聚合物微孔膜的方法，清华大学化学工程系膜技术与工程研究中心从2003年起开始从事TIPS法制备聚合物微孔膜的研究工作，获得了国家863和973等多项科技计划的资助，并取得重大突破。本文以聚丙烯（PP）、聚偏氟乙烯（PVDF）、乙烯三氟氯乙烯共聚物（ECTFE）、醋酸纤维素（CA）等四种膜材料为主线，详细介绍了清华大学TIPS法制膜技术从基础研究、关键技术突破到产业化的发展历程，及其在水处理工程中的应用情况。

Thermally Induced Phase Separation (TIPS) method is one important method for the preparation of polymer microporous membrane. Key Laboratory of Membrane Materials and Engineering, Department of Chemical Engineering in Tsinghua University has been engaged in the preparation of polymer microporous membranes by TIPS technology since 2003, funded by National 863, 973 Program and other national science and technology programs, and has made great breakthroughs. This paper introduces in detail the development of TIPS technology from basic research, key breakthrough for industrialization and related application in water treatment engineering with four membrane materials as the main line, which are polypropylene (PP), polyvinylidene fluoride (PVDF), ethylene trifluoroethylene chloride copolymer (ECTFE) and cellulose acetate (CA).
