| titleOfInvention | High-hydrophilicity polymer hybrid membrane and preparation method thereof |
| abstract | The invention relates to a high-hydrophilicity polymer hybrid membrane and a preparation method thereof, belonging to the technical field of membrane separation. Provides a method for preparing a high-hydrophilicity polymer hybrid membrane by an in-situ mineralization-assisted thermally induced phase separation method. The polyvinylidene fluoride/polyacrylonitrile blend is prepared by adopting a thermally induced phase separation method to serve as a base membrane, the base membrane is modified under an alkaline condition, then metal ions and anionic polymers are sequentially assembled on the surface of the blend membrane by adopting an in-situ growth method, hydrophilic nano particles are generated by utilizing chemical reaction between the metal ions and the anions, and inorganic particles grow in situ on the surface of the membrane by adopting an in-situ mineralization method, so that the agglomeration among the particles is avoided, the hydrophilicity of the membrane is effectively improved, the pollution resistance of the polymer membrane can be obviously improved, and the separation efficiency is improved. Has wide application prospect in the field of water treatment. |
