    • PURPOSE: A coating composition is provided to be used for manufacturing a poly(arylene ether sulfone)-based reverse osmosis membrane having a cross-linked structure and to obtain high durability and excellent salt rejection coefficient compared with a conventional polyamide-based reverse osmosis membrane. CONSTITUTION: A coating composition used for manufacturing a reverse osmosis membrane comprises: 20-50 weight% of poly(arylene ether sulfone) copolymers; 0.5-5 weight% of an epoxy resin; and an organic solvent. A method for manufacturing the reverse osmosis membrane for seawater desalting comprises: a step(S110) of manufacturing the coating composition including the poly(arylene ether sulfone) copolymers; a step(S120) of forming a mixed solution by dispersing inorganic particles on the coating composition; a step(S130) of spreading the mixed solution on the surface of a material to be coated; a step(S140) of forming a membrane by drying the mixed solution; and a step(S150) of crosslinking the inorganic particles and the poly(arylene ether sulfone) copolymers within the dried membrane.
