| titleOfInvention | Polyvinylidene fluoride-titanium dioxide hybrid membrane and preparation method and application thereof |
| abstract | A polyvinylidene fluoride-titanium dioxide hybrid membrane is prepared by the following steps: dissolving polyvinylidene fluoride in an organic solvent A, adding a mineralization inducer, stirring for 1-2 hours at 50-70 ℃ under the condition of air isolation to obtain a polyvinylidene fluoride-mineralization inducer mixed solution, dripping a titanium precursor solution into the mixed solution, stirring for 6-12 hours at 50-70 ℃ after dripping, standing and defoaming for 12-24 hours to obtain a casting solution, pouring the casting solution on a glass substrate at room temperature for scraping a film, then putting the glass substrate into a gel bath for soaking for 5-20 min for phase conversion to form a film, spontaneously dropping the film from the glass substrate, washing with deionized water, then putting the film into deionized water at 0-10 ℃ for soaking for 24-48 hours, taking out and freeze-drying to obtain a finished product; the method can effectively inhibit the agglomeration problem of the titanium dioxide nano particles in the polymer main body, and the prepared membrane has excellent anti-pollution property, simple process, easy operation and low cost. |
