| titleOfInvention | Zirconium dioxide-itaconic acid grafted PVDF hollow fiber separation membrane and preparation method and application thereof |
| abstract | The invention relates to ZrO 2 An itaconic acid grafted PVDF hollow fiber separation membrane, a preparation method and an application thereof, belonging to the field of polymer separation membranes. The hollow fiber separation membrane is an itaconic acid grafted PVDF hollow fiber separation membrane, and ZrO is mineralized and deposited on the surface of the hollow fiber separation membrane 2 . The preparation of the separation membrane comprises the following steps: (1) loading and fixing an initiator in the PVDF hollow fiber membrane; (2) preparing an itaconic acid solution, soaking the PVDF hollow fiber membrane loaded with the initiator in the step (1) in the itaconic acid solution, and reacting to prepare an itaconic acid grafted PVDF hollow fiber membrane; (3) soaking the itaconic acid grafted PVDF hollow fiber membrane obtained in the step (2) in Zr (SO) with the PH value less than 7 4 ) 2 In the solution, the biomimetic mineralization reaction is carried out to form ZrO outside the membrane 2 -itaconic acid microstructure. Compared with an unmodified membrane, the surface of the modified hollow fiber separation membrane is super-hydrophilic, the separation efficiency of the hollow fiber separation membrane on oil-water emulsion is excellent, and the pollution resistance is obviously enhanced. The preparation method is simple in preparation process, easy to operate and strong in universality. |
