    摘要: Provided are flux enhancing inclusion complexes for preparing highly permeable thin film composite membranes, and processes that include adding the flux enhancing inclusion complexes to the organic phase or aqueous phase prior to interfacial polymerization of the thin film composite membrane. The thin film composite membranes are suitable for nanofiltration, and reverse and forward osmosis. The provided processes can include contacting a porous support membrane with an aqueous phase containing a polyamine to form a coated support membrane, and applying an organic phase containing a polyfunctional acid halide and a flux enhancing inclusion complex to the coated support membrane to interfacially polymerize the polyamine and the polyfunctional acid halide to form a discrimination layer to form thin film composite membranes.
