A composite film containing COFs intermediate layer, preparation method and application thereof |
| abstract |
The invention discloses a composite film containing a COFs intermediate layer, a preparation method and application thereof; the preparation method of the composite film containing a COFs intermediate layer includes the preparation steps of a COFs-containing intermediate layer and a skin layer; A layer of COFs interlayer is modified on the surface, and then interfacial polymerization is carried out on the COFs interlayer, which significantly improves the flux and retention performance of the composite membrane; the COFs interlayer has a uniform pore size and optimizes the physical properties of the base membrane. The chemical property effectively regulates the interfacial polymerization process and the formation of the skin layer, and improves the separation performance of the membrane; the preparation process of the invention is simple and has a good application prospect in water treatment. |
