Abstract

The thermally induced phase separation (TIPS) method is one of the most versatile techniques to fabricate polymeric membranes, with distinct advantages such as a narrow pore size distribution and high reproducibility. Selecting the right solvent is arguably the most important decision to be made for fabricating high-performance membranes via TIPS. Hence, it is crucial to understand the intricate relationship between the solvent and the polymer during TIPS. In this article, we discuss the fundamental aspects of TIPS solution thermodynamics and phase inversion kinetics. Recent advances in the TIPS process and new green solvents that have been identified for fabrication of membranes are discussed in depth.
