| titleOfInvention | A kind of composite nanometer filtering film and preparation method thereof and the application in water treatment field |
| abstract | The invention discloses a kind of composite nanometer filtering films and preparation method thereof, and the application by the composite nanometer filtering film and the composite nanometer filtering film being prepared by the preparation method in water treatment field.The composite nanometer filtering film includes the supporting layer to stack together and separating layer, wherein, the separating layer is the initial composite NF membrane for the cross-linked structure that silane coupling agent of the hydroxy-end capped dimethyl silicone polymer with ethyl orthosilicate and containing amino is formed after heat cross-linking reacts in the support layer surface, then the initial composite NF membrane is post-processed in the solution of formaldehyde and phosphorous acid.Composite nanometer filtering film of the present invention not only has higher salt rejection rate and water penetration (water flux), can also be applied in water treatment field, and preparation method is simple, great prospects for commercial application. |
