| titleOfInvention | Carboxyl-containing polyethersulfone, reverse osmosis membrane, and preparation methods of the carboxyl-containing polyethersulfone and the reverse osmosis membrane |
| abstract | The invention provides carboxyl-containing polyethersulfone, a preparation method of the carboxyl-containing polyethersulfone, the carboxyl-containing polyethersulfone prepared by the method, a reverse osmosis membrane prepared from the carboxyl-containing polyethersulfone, and a preparation method of the reverse osmosis membrane. The carboxyl-containing polyethersulfone has a structure shown as the formula (I), wherein R1-R8 and R11-R24 are independently hydrogen or C1-C5 alkyl, R9 is nonexistent or C1-C5 alkylidene, R10 is hydrogen or C1-C5 alkyl, m:n is 0.1-10:1, and the number average molecular weight of the carboxyl-containing polyethersulfone is 10000-100000. The reverse osmosis membrane containing the carboxyl-containing polyethersulfone has high water flux and desalination rate and has good industrial prospect. The formula (I) is described in the specification. |
