Composite polyamide reverse osmosis membrane for desalination of seawater, comprises polyamide layer and hydrophilic coating of polyfunctional epoxy compound, formed sequentially on microporous support
The composite polyamide reverse osmosis membrane comprises a polyamide layer and a hydrophilic coating provided sequentially on a microporous support. The hydrophilic coating is formed by applying a polyfunctional epoxy compound having at least two epoxy groups, on polyamide layer and cross-linking such that a water-insoluble polymer is formed. Independent claims are included for the following: (1) method for forming a coated composite polyamide reverse osmosis membrane; (2) microporous membrane; and (3) method of producing coated microporous membrane.
