摘　　要：热诱导相分离法(TIPS)是一种简单而有效的制备聚合物微孔膜的方法。文中介绍了TIPS法制备微孔膜的步骤、特点,从热力学平衡相图和动力学相分离两方面阐明了制膜原理;综述了由TIPS法制备聚丙烯、聚乙烯、聚偏氟乙烯膜及亲水膜的最新研究进展,并对今后的研究方向提出了建议。Thermally induced phase separation (TIPS) procedure is a simple and versatile membrane preparation technique. The process and characteristics of TIPS were reviewed. The mechanism of membrane formation was explained with thermodynamic phase diagram and kinetics of phase separation. The current research of several kinds of polymer microporous membranes (PE, PVDF, PMMA, Nylon12, etc)via TIPS process was introduced.
