Two novel imide/imine-based organic cages were prepared and studied as materials for the selective separation of CO 2 from N 2 and CH 4 in Vacuum Swing Adsorption conditions. Gas adsorption on the new compounds showed selectivity for CO 2 over N 2 and CH 4 . The cages were also tested as fillers in mixed-matrix membranes for gas separation. Dense and robust membranes were obtained by loading the cages in either Matrimid ® or PEEK-WC polymers. Improved gas transport properties and selectivity for CO 2 were achieved compared to the neat polymer membranes.

Abstract
Two novel imide/imine-based organic cages were prepared and studied as materials for the selective separation of CO 2 from N 2 and CH 4 in Vacuum Swing Adsorption conditions. Gas adsorption on the new compounds showed selectivity for CO 2 over N 2 and CH 4 . The cages were also tested as fillers in mixed-matrix membranes for gas separation. Dense and robust membranes were obtained by loading the cages in either Matrimid ® or PEEK-WC polymers. Improved gas transport properties and selectivity for CO 2 were achieved compared to the neat polymer membranes.File in questo prodotto:
