Hybrid nanoparticle TFC membranes |
摘要 |
A process for preparing a reverse osmosis membrane that includes (A) providing a polyamine, a polyfunctional acid halide, and mono-hydrolyzed trimesoyl chloride; (B) combining the polyamine, polyfunctional acid halide, and mono-hydrolyzed trimesoyl chloride on the surface of a porous support membrane; and (C) interfacially polymerizing the polyamine and the polyfunctional acyl halide on the surface of the porous support membrane to form a reverse osmosis membrane comprising (i) the porous support membrane and (ii) a discrimination layer comprising a polyamide. The reverse osmosis membrane is characterized by a flux that is greater than the flux of the same membrane prepared in the absence of the mono-hydrolyzed trimesoyl chloride. |
