PERCOLATION-ASSISTED COATING OF METAL-ORGANIC FRAMEWORKS (MOFs) ON POROUS SUBSTRATES

Abstract

A percolation-assisted coating (PAC) process that combines top-down and bottom-up approaches in a continuous-flow microfluidic device to deposit metal organic frameworks (MOFs) on a porous substrate. Methods of coating a porous substrate with MOF, comprising flowing a MOF precursor composition comprising MOF secondary building units (SBUs) and combinations of SBUs suspended in a solvent through a porous substrate having a first face and a second face, thereby depositing MOF SBUs and combinations of SBUs on the first face of the porous substrate, wherein each of the MOF SBUs comprise a metal ion coordinated to an organic linker, and wherein during flowing the MOF precursor composition through the porous substrate, MOF SBUs and combinations of SBUs self-assemble into MOF crystals to provide a porous substrate coated with a thin film of MOF crystals on the first face of the porous substrate.
