Mixed-matrix membranes for CO2 separation: role of the third component

Abstract

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