High‐performance metal–organic framework (MOF)/polyimide (PI) mixed matrix membranes (MMMs) are fabricated by a facile strategy by designing the MOF/PI matrix interface via poly dopamine coating. The overall separation performance of the designed MMMs surpasses the state‐of‐the‐art 2008 Robeson upper bound for the H 2 /CH 4 and H 2 /N 2 gas pairs and approaches the 2008 upper bound for the O 2 /N 2 gas pair.
