Novel high-performance epoxyether thin-film membranes for separation of CO2 from industrial gas streams

CO2 capture from power plants and industrial exhaust streams aims at strongly reducing anthropogenic CO2 emissions, while CO2 removal from energy streams is of utmost importance in industry. Membrane-based gas separation (GS) is considered to be a viable alternative for traditional separation technologies, although current state-of-the-art membranes often lack the required separation performance. In this project, the highly tunable epoxy-ether chemistry is applied as a platform for the development of high-performance poly(epoxyether) GS membranes. These membranes are interesting for CO2 separations due to (1) high ethylene oxide content, (2) the presence of quaternary ammonium groups, (3) their highly cross-linked nature, making them plasticization-resistant, and (4) the possibility to develop them as thin films. Through (1) an elaborate parameter study and (2) testing under industrial conditions, structure-performance relationships will be obtained and used to develop GS membranes with excellent performance under industrial conditions.
