METHOD FOR PREPARING REVERSE OSMOSIS MEMBRANE, AND REVERSE OSMOSIS MEMBRANE PREPARED THEREBY

摘要

There is disclosed a method for preparing a reverse osmosis membrane, the method including: forming a first coating layer by coating an aqueous amine solution on a surface of a microporous support to have a thickness of 20 mum to 30 mum; removing an excess of the aqueous amine solution from the microporous support; and forming a second coating layer by coating an aliphatic hydrocarbon-based organic solution including acyl halide on the first coating layer to have a thickness of 10 mum to 30 mum.
