| titleOfInvention | A method for preparing PVDF blend membrane with activated carbon and cross-linking agent |
| abstract | The invention discloses a method for preparing a PVDF blended film by using activated carbon and a cross-linking agent. The method comprises the following steps: S1, preparing a film-forming solution from polyvinylidene fluoride and N,N-dimethylacetamide; S2. Mix the activated carbon and the glutaraldehyde cross-linking agent evenly; S3. Add the solution obtained in step S2 to the solution obtained in step S1, and mix evenly to obtain a film casting liquid; S4, scrape the evenly mixed film casting liquid on the glass On the plate, evaporated in the air, cured, soaked, and dried to obtain a PVDF blend film. The PVDF blended membrane of the present invention is added with activated carbon when casting the membrane, so that the membrane not only has the advantages of the PVDF membrane, but also has the effect of accelerating the degradation of dyes. |
