    摘要: A reverse osmosis separation membrane includes a porous support, a separation active layer formed on the supporting layer, and a ultra hydrophilic layer formed on the separation active layer. The ultra-hydrophilic layer includes a complex metal oxide including at least one metal element selected from the group consisting of Ti(IV), Zr(IV), Sn(IV) and Al(III), and Si, and an organic compound containing a hydrophilic group making a physical or chemical bond with Ti(IV), Zr(IV), Sn(IV) or Al(III) among the complex metal oxide. A method of manufacturing the reverse osmosis separation membrane also is provided. A reverse osmosis membrane including a single coating layer and having an improved durability, chlorine-resistance and antifouling properties may be provided.

    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 μm to 30 μm; 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 μm to 30 μm.
