| titleOfInvention | Preparation method of anti-fouling composite nanofiltration membrane with strong stability |
| abstract | The invention discloses a preparation method of a strong-stability anti-fouling composite nanofiltration membrane. After simple activation, water phase impregnation and oil phase impregnation are carried out on a hydrophobic polytetrafluoroethylene microporous membrane, anti-fouling modification and post-treatment processes are added, and a large amount of hydrophilic silicon dioxide spherical substances are generated through a grafting reaction on the surface of the membrane, so that the anti-fouling composite nanofiltration membrane with strong stability is obtained. The anti-fouling modification layer is grafted on the separation layer of the nanofiltration membrane, is not easy to fall off, has lasting and stable anti-fouling effect, can be used in severe environments such as strong acid, strong alkali, high temperature and the like for a long time, and greatly expands the application range of the nanofiltration membrane. |
