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/N2mixtures, 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. Into the mix: Two ionic liquids (ILs) are supported on metal–organic frameworks (MOFs) for CO2/N2separation studies. The IL@MOF structures work as fillers in a polymer matrix membrane. Tetramethylguanidiniumazide, when combined with MOF‐5 and dispersed in Matrimid®, gives rise to a composite that is highly robust and with improved membrane permeability and CO2selectivity with only 2 % of IL@MOF load in the membrane. |
