| titleOfInvention | Preparation method of polyacrylonitrile-based super-hydrophilic membrane |
| abstract | The invention designs a preparation method of a polyacrylonitrile-based super-hydrophilic membrane, which is characterized in that the preparation method of the super-hydrophilic membrane is prepared according to the following steps: firstly, preparing a polyacrylonitrile super-hydrophilic membrane: firstly, preparing a polymer solution from polyacrylonitrile with a certain content and an active additive, coating the polymer solution to form a film, and then placing the film in an alkaline solution for phase conversion to prepare a polyacrylonitrile super-hydrophilic film; preparing a hydrochloric acid solution with a certain concentration, washing the membrane obtained in the step one by deionized water, immersing the membrane into the hydrochloric acid solution obtained in the step two for a certain time, and performing post-treatment to obtain the super-hydrophilic separation membrane. The method is simple to operate, the super-hydrophilic surface is constructed in one step, and the prepared super-hydrophilic polyacrylonitrile membrane has excellent hydrophilicity and contact angle<3 o The paint is completely soaked within 0.5s, and the surface hydrophilic structure is not changed, so that the paint has a permanent hydrophilic characteristic. The method is suitable for preparing the super-hydrophilic polyacrylonitrile-based ultrafiltration membrane and the super-hydrophilic polyacrylonitrile-based microfiltration membrane, and has wide application prospect. |
