| titleOfInvention | Preparation method of anti-biological-pollution PVDF (polyvinylidene fluoride) film |
| abstract | The invention discloses a preparation method of a PVDF (polyvinylidene fluoride) film modified by silver phosphate modified nano negative ion powder. The preparation method comprises the steps of firstly, obtaining nano silver phosphate by adopting an ion exchange method, and modifying negative ion powder by nano silver phosphate to obtain negative ion powder with different silver carrying capacity; secondly, adding a proper amount of the silver-carrying negative ion powder into a PVDF casting film solution, and preparing the modified PVDF film containing the silver-carrying negative ion powder by adopting a phase inversion method. By virtue of peculiar nanometer size effect and surface energy of the silver-carrying negative ion powder, the PVDF film is endowed with effective anti-biological-pollution capability, the hydrophilicity of the PVDF film is improved, and the flux recovery rate of the PVDF film is increased; in addition, the preparation method of the modified PVDF film is simple and easy to adjust and control. |
