In Situ Incorporation of Macromolecules in Zr-MOF Membranes for Separation of Organic Azeotropic Mixtures.

ABSTRACT: Metal-organic framework (MOF) membranes with adjustable angstrom-scale channels and versatile topological structures are promising for molecular separation. However, it remains a challenge to construct MOF membranes with precisely tuned pore sizes and tailored molecular affinity for achieving high-efficiency liquid molecular separation, particularly for organic azeotropic mixtures. Herein, we proposed an in situ macromolecule incorporation strategy to fabricate a Zr-MOF membrane with a tunable pore microenvironment for pervaporation separation of butanol-water and ethanol-ethyl acetate azeotropic mixtures. The membranes were prepared by an in situ interfacial growth process. The amino macromolecules (poly-(ether imide), PEI) were dispersed into a metal cluster solution, followed by coordin
