Abstract
This invention provides a new high flux reverse osmosis (RO) membrane comprising a nanoporous polyethersulfone (PES)/polyethylene oxide-polysilsesquioxane (PEO-Si) blend support membrane (PES/PEO-Si) comprising a polyethylene oxide-polysilsesquioxane (PEO-Si) polymer and a polyethersulfone (PES) polymer, a hydrophilic polymer inside the pores on the skin layer surface of the polyethersulfone/polyethylene oxide-polysilsesquioxane blend support membrane, and a thin, nanometer layer of cross-linked polyamide on the skin layer surface of said polyethersulfone/polyethylene oxide-polysilsesquioxane blend support membrane, and a method of making such a membrane. This invention also provides a method of using the new high flux reverse osmosis membrane comprising nanoporous PES/PEO-Si blend support membrane for water purification.
