Effective functionalization of porous polymer fillers to enhance CO2/N2 separation performance of mixed-matrix membranes

A series of porous organic polymers (denoted as PBP-x) possessing various functional groups was synthesized via Friedel�Crafts alkylation followed by post-synthetic functionalization using amine and sulfonic groups. These functionalized porous polymers were incorporated into an in-house polyimide...
