| titleOfInvention | A kind of renewable PVDF membrane with adsorption function and preparation method thereof |
| abstract | The invention discloses a renewable PVDF membrane with adsorption function and a preparation method thereof. The preparation steps of the PVDF membrane are: S1, adopting a polymer/non-solvent co-induced phase separation method to introduce at least a The active group of the hydroxyl group is used to obtain an active PVDF membrane; S2, a supramolecular compound is grafted on the active PVDF membrane by a chemical modification method; the supramolecular compound is α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin , one or more in hydroxypropyl-β-cyclodextrin; S3, put the PVDF membrane grafted with supramolecular compound into water and soak for at least 72h, namely obtain the renewable PVDF membrane with adsorption function; The preparation method of the renewable PVDF membrane with adsorption function enables the PVDF membrane to have molecular recognition ability while ensuring that the adsorption sites are fully displayed to improve the adsorption effect, and the preparation process is simple and mild, and does not destroy the original structure of the PVDF membrane; The membrane also has the performance of renewable recycling, the renewable process is simple, and it is easy to be recycled. |
