摘要：

热致相分离（TIPS）法制备的微孔膜因具有孔隙率高、渗透通量大、孔径分布窄、孔径可调、机械强度高等优势而备受关注。在TIPS法制备微孔膜过程中，稀释剂的选择对相分离过程尤为重要，直接决定了微孔膜的结构与形态。本文综述了稀释剂在TIPS法制备微孔膜中的研究进展。首先介绍了稀释剂的筛选依据；其次重点阐述了稀释剂种类对所制微孔膜的形貌、结构与性能的影响；最后指出，通过结合机器学习、深度学习等技术构建精准稀释剂选择的理论模型，开发绿色、高效的稀释剂是TIPS法制备微孔膜研究的重点方向之一。

Microporous membranes prepared by thermally induced phase separation (TIPS) have attracted much attention due to their high porosity, large permeation flux, narrow pore size distribution, adjustable pore size, and high mechanical strength. In the preparation of microporous membranes by TIPS method, the selection of diluent is particularly important for the phase separation process, which directly determines the structure and morphology of the microporous membranes. In this study, the research progress of diluents in the preparation of microporous membranes by thermally induced phase separation is reviewed. Firstly, the selection principle of the diluent is introduced. And then, the effects of different diluents on the morphology, structure and performance of the prepared microporous membrane are elaborately elucidated. Finally, it is pointed out that combining the machine learning, deep learning, and other technologies to build a precise theoretical model for diluent selection, the development of green and efficient diluents is one of the key research directions on the microporous membrane preparation by TIPS method.
