Method for preparing two-dimensional covalent organic framework ultrathin nanosheet material composite membrane and application |
| abstract |
A method for preparing a two-dimensional covalent organic framework ultrathin nanosheet material composite membrane and application thereof. The method comprises the following steps of (1) preparing two-dimensional covalent organic framework ultrathin nanosheets: mixing a two-dimensional layered covalent compound precursor with an organic solvent, and performing wet ball milling treatment; (2) preparing a two-dimensional covalent organic framework nanosheet pure-phase film on the surface of the porous material by adopting a hot dropwise adding method; (3) preparing a two-dimensional covalent organic framework nanosheet and ionic liquid composite membrane twice by adopting a hot-drop method; (4) and drying the composite membrane. Compared with a two-dimensional covalent organic framework nanosheet pure phase membrane, the gas separation performance of the two-dimensional covalent organic framework ultrathin nanosheet composite membrane prepared by the method is remarkably improved. |
