Predictive Models for Mixed-Matrix Membrane Performance: A Review

Researchers share their views on the latest scientific and technological advances in the development of theoretical models focused on the prediction of the gas separation performance of mixed-matrix membranes (MMM). An overview of the latest MMMs using various kinds of fillers is introduced for better understanding. The status, applicability, and future theoretical research for estimating the gas separation performance of MMMs are highlighted and validated. The mixed-matrix membranes (MMMs) where inorganic fillers in solid, liquid, or solid and liquid forms are dispersed in a polymer matrix, have been identified to provide a solution to the upper-bound trade-off limit of the polymeric membranes while addressing the brittleness obstacle of the inorganic membranes. MMMs are also expected to combine the potential advantages in separation performances of inorganic and polymer membranes.
