AN IMPROVED OXIDATIVELY RESISTANT MEMBRANE PROCESS FOR MAKING SAME AND METHOD OF DESALINATING A SALINE WATER THEREWITH

摘要

The invention provides a novel thin film composite or coated membrane suitable for reverse osmosis, ultrafiltration and microfiltration applications, and having a porous polymeric substrate with one or more microporous layers to which a thin film or coating comprising a sulfonated polyarylether is attached substantially to provide an oxidatively stable, thin hydrophilic film or coating layer, and a method for manufacturing and using the same.
