Achieving percolation pathways in a metal-organic framework (MOF)–based mixed matrix membrane (MMM) without compromising its mechanical properties is challenging. We developed phase separated (PS)–MMMs with an interconnected MOF domain running across the whole membrane. Through demixing two immiscible polyimides, the MOF particles were selectively partitioned into one of the preferred polymer domains at over 50 volume % local packing density, leading to a percolated network at only 19 weight % MOF loading. The CO
