Thermally rearranged (TR) polymers are unique high-performance materials with rigid
aromatic rings like benzoxazoles and benzimidazoles, that are produced/transformed by …

Polymeric membranes for gas separations have experienced rapid growth over the past few
decades, and extensive research has been performed to develop high-performance polymer …

One critical problem confronted with gas separation industrial is membrane with high
permeability, selectivity, mechanical strong and reliability. Here, we reported a high …

The implementation of synthetic polymer membranes in gas separations, ranging from
natural gas sweetening, hydrogen separation, helium recovery, carbon capture …

Membrane-based gas separation technique shows great potential in CO 2 elimination from
natural gas and N 2 enrichment from compressed air. In this study, a double-decker-shaped …

One important challenge in advanced gas separation membranes is breaking the trade-off
effect between gas permeability and selectivity. Here, we developed a method by combining …

Carbon molecular sieves (CMSs) derived from polymer precursors that can be prepared at
scale are attractive for various energy-efficient sorption and separation technologies, such …

Cross-linked polymers for gas separation have significant advantages in increasing gas
selectivity and separation stability. However, the cross-linking strategies unavoidably form …

Herein, we developed a new diamine monomer termed TA-BOC that features a tert-
butoxycarbonyl (t-Boc) protected group. This t-Boc group could shield one of the reactive …

By employing a variation of the polyamidation method using in situ silylated diamines and
acid chlorides, it was possible to obtain a rod-type polyamide: poly (p-phenylene …
