MANUFACTURING METHOD FOR POLYAMIDE-BASED REVERSE OSMOSIS MEMBRANE AND POLYAMIDE-BASED REVERSE OSMOSIS MEMBRANE MANUFACTURED THEREBY

摘要

PURPOSE: A manufacturing method of a polyamide-based reverse osmosis membrane and the polyamide-based reverse osmosis membrane manufactured thereby are provided to easily manufacture the polyamide-based reverse osmosis membrane with naphthalene dicarboxylic acid chloride. CONSTITUTION: A manufacturing method of a polyamide-based reverse osmosis membrane includes the following steps: coating a microporous support with a multi-functional amine aqueous solution; forming a membrane by interfacial polymerization by contacting an aliphatic hydrocarbon system organic solution including Naphthalene dicarboxylic acid chloride on the microporous support coated with the multi-functional amine aqueous solution; and washing and drying the acquired membrane. The Naphthalene dicarboxylic acid chloride is mixed with multi-functional acyl halide.
