Abstract：
 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.
