Published: May 2019

A general, green, efficient, and easily scalable methodology has been developed to more effectively incorporate (disperse) metal-organic frameworks (MOFs) into polymer technologies via solid state synthesis of any MOF nanocrystals within soluble mesoporous polymers. The resulting solid hybrid materials (pellets) can be directly transformed into colloidal MOF polymeric suspensions (inks) by simple dissolution in organic solvents. The straightforward use of novel colloidal MOF polymeric inks as ultimate additive for mixed matrix membranes resulted in unprecedented snakeskin microstructure exhibiting outstanding selectivity for CO over N (>100) from post-combustion flue gas at very low and well-dispersed MOF nanocrystal concentrations ranging from 1 to 7 wt %. This novel methodology brings one of the most versatile routes yet reported to transform any MOF into more functional forms that can be directly integrated into any conventional polymer technology at the commercial scale.
