ZIF-11 loaded 6FDA-DAM mixed matrix membranes were synthesized.
ZIF-11 particles dispersed homogeneously in 6FDA-DAM polymer with good interfacial filler-matrix adhesion.
Significant increase observed in gas permeability with increase in the content of ZIF-11 in MMMs.
Addition of ZIF-11 particles to the 6FDA-DAM matrix attained their performance closer to the 2008 Robeson upper bound.
