Recent progress in the interfacial polymerization process for CO2 separation membrane fabrication

Nowadays, global warming caused by the increasing levels of CO2 has become a serious environmental problem. Membrane separation technology has demonstrated its promising potential in carbon capture due to its easy operation, energy-efficientness and high efficiency. Interfacial polymerization process, as a facile and well-established technique for preparing membranes with a thin selective layer, has been widely used for fabricating commercial reverse osmosis and nanofiltration membranes in water treatment domain. To push forward such an interfacial polymerization process in the research of CO2 separation membranes, herein we make a review on the regulation and research progress of the interfacial polymerization membranes for CO2 separation. First, a comprehensive and critical review of the progress in the monomers, nanoparticles and interfacial polymerization process optimization for preparing CO2 separation membrane is presented. In addition, the potential of molecular dynamics simulation and machine learning in accelerating the screen and design of interfacial polymerization membranes for CO2 separation are outlined. Finally, the possible challenges and development prospects of CO2 separation membranes by interfacial polymerization process are proposed. It is believed that this review can offer valuable insights and guidance for the future advancement of interfacial polymerization membranes for CO2 separation, thereby fostering its development.
