Chemical grafting or crosslinking of polyimide chains are known to be feasible approaches to increase polymer gas-pair selectivity and specific gas permeance. Different co-polyimides; 6FDA-ODA and 6FDA-ODA:DABA were synthesized using a two-step conde

Membrane gas separation is an emerging technology used for the separation of CO2. Matrimid® 5218, one of the current polymers used in membrane gas separation, has good selectivity, but poor CO2 permeability. We wondered if its CO2 permeability could

6FDA based polyimides possess outstanding properties, with a high free volume fraction entailing in high permselectivity properties for gas separation processes. However, they are very sensitive to aging process. Copolyimdes 6FDA–DAM:DABA were synt

The ZIF-8 zeolitic imidazolate framework (ZIF) is known to enhance gas separation properties of a mixed matrix membrane (MMM) due to its inherent molecular sieving properties. We prepared ZIF-8 nanoparticles (NPs) in several particle sizes, character
