Mixed-Matrix Membranes for CO2 Separation: Role of the Third Component
Mixed-matrix membranes (MMMs) have exhibited excellent performances for CO2 separation, while it is still an ongoing challenge in the enhancement of separation performance through optimization of their structures. Recent works demonstrated that the introduction of a tertiary component may play a positive role on improving the separation performance of two-component MMMs (polymer matrix and filler), showing a great promise for addressing this challenge. Herein, recent advances in the different types of tertiary components adopted in MMMs for CO2 separation are reviewed, including small molecules, macromolecules, and porous materials, and a concise summary and outlook are outlined toward ternary MMMs fabrication.
