| titleOfInvention | A kind of preparation method of super-hydrophobicity pvdf membrane |
| abstract | The invention discloses a kind of preparation methods of super-hydrophobic pvdf membrane.This method, which specifically includes that, prepares PVDF casting solution, prepares mixed type coagulating bath；The hollow-fibre membrane for preparing nascent plate membrane or being spun into through hollow spinning head；Above-mentioned primary membrane is stood in air and is placed in coagulating bath, removal residual organic matter is impregnated through deionized water after being fully cured, obtains super-hydrophobicity PVDF composite membrane；The zero defect step pore structure of spherical accumulation is presented by PVDF super-hydrophobic film prepared by this method, the micro-nano dual microtexture of similar lotus leaf surface is presented in surface layer and the internal PVDF microsphere surface being precipitated, therefore not only film surface but also fenestra embody superhydrophobic characteristic, fundamentally improve the anti-wettability energy of film；Super-hydrophobic pvdf membrane preparation method disclosed by the invention has many advantages, such as the simple strong operability of preparation process, avoids the unabiding drawback of resist wet effect of simple film surface modifying super hydrophobicity, is suitable for the membrane process such as membrane distillation, film absorption. |
