Metal-organic Framework Supported On Porous Polymer

Abstract

The growth of continuous MOF membranes on porous polymeric supports is reported, wherein a dip-coating procedure is used to deposit a layer of seed MOF nanocrystals on the surfaces of porous polymers, preferably in the form of hollow fibers, and polycrystalline MOF membranes are subsequently grown at temperatures as low as 65� C. from precursor solutions. The present work opens the road to inexpensive and scalable fabrication of MOF membranes for large-scale separation applications.
