| titleOfInvention | A kind of polyvinylidene fluoride/polyacrylonorganic-inorganic organic-inorganic hybrid hollow fiber membrane and preparation method thereof |
| abstract | The present invention relates to a kind of polyvinylidene fluoride/polyacrylonorganic-inorganic organic-inorganic hybrid hollow fiber membrane and preparation method thereof, casting solution of the present invention is composed as follows: Kynoar, 14-25%; Polyacrylonitrile, 1-12%; Organic and inorganic complex additive 4-15%; Solvent, 50-80%.Finished product polyvinylidene fluoride/polyacrylonorganic-inorganic organic-inorganic hybrid hollow fiber membrane is prepared by dry-jet wet-spinning silk technique after casting solution prepares.Compared with prior art, because the present invention with the addition of a kind of novel organic and inorganic complex additive while the hydrophilic blend of interpolation, further increase intensity and the hydrophily of film silk, adopt Kynoar/polyacrylonitrile organic and inorganic hollow-fibre membrane that the present invention produces, the purer polyvinylidene fluoride film of performance has had and has improved significantly, has greatly widened the application of film. |
