Abstract
Official abstract text for this publication.
The present invention relates to a reverse osmosis membrane including: a porous support; and a polyamide active layer formed on the porous support and including zeolite, surface-treated with a compound having at least one functional group selected from a group consisting of an amino group and a glycidyl group, and a method of manufacturing the same.
First claim
Opening claim text (preview).
1 . A reverse osmosis membrane comprising: a porous support; and a polyamide active layer formed on the porous support and including zeolite, surface-treated with a compound having at least one functional group selected from a group consisting of an amino group and a glycidyl group. 2 . The reverse osmosis membrane of claim 1 , wherein the compound is a silane compound having the at least one functional group selected from the group consisting of the amino group and the glycidyl group. 3 . The reverse osmosis membrane of claim 1 , wherein the surface-treated zeolite is zeolite, surface-treated with the compound having the amino group, and the amino group is chemically bonded to the polyamide active layer. 4 . The reverse osmosis membrane of claim 1 , wherein the zeolite has an MFI (Zeolite Socony Mobil-five) type structure, an LTA (Zeolite A) type structure, or a FAU(Faujasite) type structure. 5 . The reverse osmosis membrane of claim 1 , wherein a difference between a maximum particle diameter and a minimum particle diameter of the surface-treated zeolite is 10 to 200 nm. 6 . The reverse osmosis membrane of claim 1 , wherein an average particle diameter of the surface-treated zeolite is 50 to 200 nm. 7 . A method of manufacturing a reverse osmosis membrane, the method comprising: forming a porous support; and forming a polyamide active layer on the porous support by interfacially polymerizing a polyfunctional amine solution including zeolite surface-treated with a compound having at least one functional group selected from a group consisting of an amino group and a glycidyl group and a polyfunctional acid halide compound solution. 8 . The method of claim 7 , wherein the surface-treated zeolite is included in an amount of 0.001 wt % to 1 wt %, with respect to 100 wt % of the polyfunctional amine solution.
