The invention discloses a CNTs (at) rGO hybrid polydimethylsiloxane membrane, a preparation method and application, and relates to the field of membrane separation technologies and new materials, and the preparation method comprises the steps of membrane casting solution preparation, flat membrane scraping and thermal crosslinking. A nonionic surfactant molecular chain is wound on the surfaces of the CNTs one-dimensional nanowires and the rGO two-dimensional nanosheets, so that surface charge repulsive interaction and steric hindrance repulsive interaction are provided, and agglomeration of the CNTs and the rGO is prevented; meanwhile, as a'bridge ', adsorption of CNTs on the surface of rGO is promoted, and a CNTs (at) rGO three-dimensional layered stacked structure is formed through in-situ self-assembly in a PDMS film. The three-dimensional nano-structure has relatively strong adsorption performance on organic solvent molecules, and uniform dispersion of the three-dimensional nano-structure ...

The invention discloses an MXene nanosheet/polyvinyl alcohol mixed matrix pervaporation membrane, a preparation method and application, and relates to the field of membrane separation technologies and new materials, and the preparation method comprises the steps of preparation of a mixed matrix membrane casting solution, high-speed centrifugal coating, drying and thermal crosslinking. MXene nanosheets in the PVA substrate are horizontally spread at a low rotating speed of a centrifugal field, migrate to the bottom of the PVA substrate at a high rotating speed, and are finally stacked at the bottom of the PVA mixed substrate separation layer layer by layer. Therefore, the compatibility and the binding force of the PVA mixed matrix separation layer and the hydrophobic support membrane are improved. Meanwhile, the MXene nanosheets which are stacked layer by layer and self-assembled construct an interlayer hydrophilic permeation channel, so that the alcohol/water separation performance of the ...

The invention discloses a method for preparing a covalent organic framework composite membrane through confinement interfacial polymerization reaction and application of the covalent organic framework composite membrane, and relates to the field of membrane separation technologies and new materials, and the preparation method comprises the steps of preparation of an organic polymer solution, preparation of an organic phase monomer solution and preparation of a water phase monomer solution and interfacial polymerization. By changing the molecular weight and the type of a polymer and adjusting the steric hindrance of a high-molecular aqueous solution to water-phase monomer molecules, the diffusion rate of the water-phase monomer molecules to the surface of the film is regulated and controlled, the reaction of water-phase monomers and organic-phase monomers is limited on the surface of a base film, crystallization and growth of a COFs film are promoted, and the defect-free COFs composite film ...
