| titleOfInvention | Preparation method of antibacterial and pollution-resistant PVDF ultrafiltration membrane for water filtration |
| abstract | The invention discloses a preparation method of an antibacterial and pollution-resistant PVDF ultrafiltration membrane for water filtration, which mainly takes N-methyl pyrrolidone as a solvent, adopts polyethylene glycol solution to blend modified polyvinylidene fluoride material, and coats the modified polyvinylidene fluoride material to form a membrane so as to obtain a primarily modified polyvinylidene fluoride membrane; immersing the polyvinylidene fluoride membrane in a solution of silver-loaded chitosan to obtain a modified PVDF microporous membrane; the polyvinylidene fluoride microporous membrane prepared by the method has better hydrophilicity, can kill surface microbial bacteria, can reduce the attachment amount of protein in sewage, can inactivate the protein and effectively prolong the service life of the polyvinylidene fluoride membrane. |
