| titleOfInvention | Organic-inorganic composite membrane and preparation method thereof |
| abstract | The invention discloses an organic-inorganic composite membrane and a preparation method thereof. The organic-inorganic composite membrane is prepared by the following steps: (1) preparing organic film-forming polymer, polar copolymer and solvent into film-forming liquid; (2) transferring the membrane-forming liquid into a membrane-forming coagulating bath to prepare an organic ultrafiltration membrane; (3) and (3) loading inorganic particles on the surface and inside of the organic ultrafiltration membrane prepared in the step (2) by an alternate immersion method to obtain the organic-inorganic composite separation membrane. The composite membrane has the characteristics of high hydrophilicity, high flux and high retention rate of dye; and the preparation method is simple and feasible and is suitable for continuous and stable production. |
