| titleOfInvention | Method for preparing reverse osmosis membrane and reverse osmosis membrane prepared thereby |
| abstract | The present application relates to a method of preparing a reverse osmosis membrane and a reverse osmosis membrane prepared thereby. The preparation method comprises the following steps: (1) contacting a porous polymer supporting layer with an amine monomer aqueous phase solution containing an antioxidant, and then contacting the porous polymer supporting layer contacted with the aqueous phase solution with an organic phase solution containing an acyl chloride monomer, or contacting the porous polymer supporting layer with the organic phase solution containing the acyl chloride monomer, and then contacting the porous polymer supporting layer contacted with the organic phase solution with the amine monomer aqueous phase solution containing the antioxidant; (2) and carrying out post-treatment and drying to obtain the reverse osmosis membrane. The functional layer of the reverse osmosis membrane prepared by the method has high crosslinking degree, so that the repeated cleaning resistance of the reverse osmosis membrane is improved, and the service life of the reverse osmosis membrane is greatly prolonged. |
