| titleOfInvention | A kind of preparation method of organic-inorganic composite ultrafiltration membrane based on carboxyl-containing polyaryletherketone and graphene oxide |
| abstract | The invention provides a preparation method of an organic-inorganic composite ultrafiltration membrane containing carboxyl polyaryl ether ketone and graphene oxide, belonging to the technical field of ultrafiltration membrane separation. The ultrafiltration membrane uses carboxyl-containing polyaryletherketone as a matrix and graphene oxide as a filler. Graphene oxide contains a variety of functional groups, which are connected with the main chain of the matrix polymer by hydrogen bonds, and are prepared by solution blending. The method provided by the invention is to prepare carboxyl-containing polyaryl ether ketone by nucleophilic polycondensation reaction, and prepare an organic-inorganic composite ultrafiltration membrane by solution blending method. The organic-inorganic composite ultrafiltration membrane of the present invention has a pure water flux of 495.3 L/m 2 h, a bovine serum albumin (BSA) rejection rate of up to 94.4%, and a flux recovery rate of 69.9%. That is, the obtained organic-inorganic ultrafiltration membrane containing carboxyl group polyaryletherketone and graphene oxide has good hydrophilicity, high flux, pollution resistance, cleaning resistance, and low production cost. |
