Abstract

Immobilization of ionic liquids (ILs) into 3D metal–organic frameworks (MOFs) is reported. The incorporation of these composites in a polyimide-based matrix (Matrimid® 5218) to yield [IL@MOF]@Matrimid® 5218 is an efficient strategy to improve the permeability and selectivity toward CO2/N2 mixtures, presenting also a remarkable improvement in membrane flexibility and mechanical resistance. Using MOF-5, a crystalline phase different to its original phase is obtained after the incorporation of hydrated IL without loss of adsorptive properties.
