Efficient anti-pollution nanofiber composite membrane for liquid-liquid membrane extraction and preparation method thereof |
| abstract |
The invention discloses a liquid-liquid membrane extraction efficient anti-pollution nanofiber composite membrane and a preparation method thereof. And preparing a PDMS selective layer on the PVDF/non-woven fabric nanofiber supporting layer by an electrostatic spraying technology so as to selectively extract organic matters. AgNPs materials or grafted Ag-MOFs materials grow in situ on the PDMS selection layer by a membrane modification method to prepare two different modification layers so as to achieve the aims of sterilization and stain resistance. The invention can effectively improve the long-term anti-pollution performance of the composite membrane, enables the membrane to keep excellent long-term organic matter mass transfer effect, and has excellent selectivity and long-term stability. |
