Abstract

Reverse osmosis membranes made by interfacial polymerization of a monomer in a nonpolar (e.g. organic) phase together with a monomer in a polar (e.g. aqueous) phase on a porous support membrane. Interfacial polymerization process is disclosed for preparing a highly permeable RO membrane, comprising: contacting on a porous support membrane, a) a first solution containing 1,3-diaminobenzene, and b) a second solution containing trimesoyl chloride, wherein at least one of solutions a) and b) contains nanoparticles when said solutions are first contacted, and recovering a highly permeable RO membrane.

Claims (7)

1 . An interfacial polymerization process for preparing a highly permeable RO membrane, comprising:

contacting on a porous support membrane,

a) a first solution containing a polyfunctional acyl halide monomer, and

b) a second solution containing a polyamine monomer,

wherein a metal beta-diketonate compound is present in a) or b) or both during the polymerization reaction,

wherein at least one of solutions a) and b) contains nanoparticles; and

recovering a highly permeable RO membrane.
