Anti-wetting super-hydrophobic membrane and preparation method thereof |
| abstract |
The invention relates to an anti-wetting super-hydrophobic membrane and a preparation method thereof 2 PDMS "sandwich" composite layers. The composite layer has a rough structure and low surface energy, the membrane has super-hydrophobicity, and the anti-wetting property is high in the membrane distillation process. The membrane is used for carrying out direct contact type membrane distillation treatment on the water body containing the surfactant, so that the membrane distillation operation time can be obviously prolonged, the stable operation time is more than 20 times of that of a PVDF original membrane, and the water production capacity is improved by more than 15 times. |
