Nano composite cellulose acetate forward osmosis membrane and preparation method thereof |
| abstract |
The invention discloses a nano composite cellulose acetate forward osmosis membrane and a preparation method thereof, wherein the forward osmosis membrane comprises: the invention also provides a membrane preparation technology, namely nano particles are added into the membrane by using an in-situ back diffusion method while the membrane is formed by phase separation and membrane formation under the non-solvent effect, the nano particles provide more water channels for the forward osmosis membrane, the mass transfer resistance and the tortuosity are reduced, the problem that the conventional forward osmosis membrane cannot simultaneously have high water flux and high retention rate is solved, and a certain pressure resistance of the forward osmosis membrane is provided. |
