| titleOfInvention | Polyamide Reverse Osmosis Composite Membrane and Manufacturing Method Thereof |
| abstract | The present invention relates to a polyamide reverse osmosis composite membrane and a method for manufacturing the same, and more particularly, (a) an aqueous solution containing a reactive primary amine monomer comprising two or more quaternary amine salts in a hydrocarbon main chain. The present invention relates to a polyamide reverse osmosis composite membrane prepared by interfacial polymerization of an aqueous amine solution containing multiple quaternary amine salts and (b) an organic solution of a polyfunctional acyl halide monomer, which is an amine reactive compound, on the surface of a porous support.n n n In the polyamide reverse osmosis composite membrane of the present invention, conventionally, various quaternary amine salts, alcohols, and polar solvents are additives by adding and using multiple quaternary amine salts alone to the primary aqueous amine solution containing a reactive primary amine monomer. It is possible to prepare a polyamide reverse osmosis composite membrane having improved water permeability and salt rejection than when used as. |
