A water-treatment separation membrane with good antifouling properties includes a support having pores, a polyamide layer formed on the support, and a passivation layer comprising specific materials formed on the polyamide layer.

Polyamide water-treatment separation membrane with improved antifouling properties and manufacturing method thereof

A water treatment separation membrane includes a support having pores, a polyamide layer formed on the support, and a passivation layer formed on the polyamide layer by using an aqueous solution including an amine-containing compound, an epoxy-containing compound and a fluorine-containing compound.

Separation membrane having excellent antifouling properties for water treatment and manufacturing method thereof

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.
