| titleOfInvention | Preparation method of zeolite imidazolate framework/polyvinylidene fluoride hybrid membrane |
| abstract | The invention belongs to the technical field of membrane preparation, and particularly relates to a preparation method of a zeolite imidazolate framework/polyvinylidene fluoride hybrid membrane, which comprises the following steps: firstly, drying polyvinylidene fluoride and then soaking the polyvinylidene fluoride in a polyvinyl alcohol solution; and then soaking the soaked polyvinylidene fluoride in a polyethyleneimine solution, cleaning, then soaking in a zeolite imidazole ester framework solution, cleaning, and finally adding a polyacrylic acid solution to obtain the zeolite imidazole ester framework/polyvinylidene fluoride hybrid membrane. The invention simplifies the film making process, is convenient to operate, has high efficiency and good production repeatability; according to the invention, the zeolite imidazole ester framework is used for modifying the substrate (polyvinylidene fluoride), so that the stability, hydrophilicity and pollution resistance of the polyvinylidene fluoride are effectively improved. |
