| titleOfInvention | A kind of antibacterial hydrophilic ultrafiltration membrane and preparation method thereof |
| abstract | The invention belongs to the technical field of preparation of ultrafiltration membrane materials, in particular to an antibacterial hydrophilic ultrafiltration membrane and a preparation method thereof; Dimethylamino) propane sulfonate (DMAPS) and quaternized carboxymethyl chitosan (QCTS) were introduced into the ultrafiltration membrane, and QCTS was introduced into the ultrafiltration membrane by blending, giving the ultrafiltration membrane a good quality. With certain antibacterial properties, the membrane is treated with oxygen plasma to generate active sites on the surface of the membrane, and then under the simultaneous action of ultraviolet light and initiator, the hydrophilic monomer DMAPS is grafted on the surface of the ultrafiltration membrane. Endows the ultrafiltration membrane with better hydrophilic properties. It ensures that the ultrafiltration membrane is hydrophilic and antibacterial modified under the premise of high rejection rate and high flux, which provides a new idea for the field of ultrafiltration membrane technology. |
