| titleOfInvention | Ultrafiltration membrane having hydrophilic and antibacterial properties and preparation method thereof |
| abstract | OF THE DISCLOSURE nThe present disclosure relates to a high-flux ultrafiltration membrane having hydrophilic and nantibacterial properties and a preparation method thereof, and belongs to the technical field of npolymeric membrane materials. The ultrafiltration membrane is prepared by dissolving a nmembrane-forming polymer and a pore-forming agent into an organic solvent to obtain a casting nsolution, forming a membrane with a phase transformation method and storing the membrane in a nwet state; and the casting solution is composed of the following components by mass percent: n16-20% of the polymer, 1-8% of povidone iodine (PVPI) and 72-83% of the organic solvent. The npresent disclosure uses the PVPI as the pore-forming agent and the antibacterial agent. During nmembrane formation, the PVPI is dissolved in the non-organic solvent to form a great number of npores in the membrane. And meanwhile, owing to the complexiation between the PVPI and the npolymer, a part of the PVPI is migrated to the surface of the membrane during the phase ntransformation, such that the membrane achieves the antibacterial property. As a part of the PVPI is nlost during membrane filtration, the membrane may be immersed into the PVPI aqueous solution nfor a certain time to restore the PVPI content on the surface of the membrane. The method is simple nand practicable, and can be industrially applied to protein concentration or wastewater biotreatment. nABSTRACT DRAWING - FIG 3 n10 n17931816_1 (GHMatters) P116903.AUn- 1/2 nFIG 1 nSPI n4% FWI l nNumber of waves (cm-) nFIG 2 n17931803_1 (GHMatters) P116903.AU |
