Zusammenfassung: | The invention discloses a novel nano atomic seawater desalination film and a preparation method and an application thereof. The preparation method comprises the steps: providing a substrate, and growing a nano atomic graphene film on the surface of the substrate by a chemical vapor deposition method; and making a water-soluble monomer and a non-water-soluble monomer undergo an interface polymerization reaction to fill cracks and defects in the graphene film, so as to obtain the novel nano atomic seawater desalination film. In the method, the nano atomic carbon film is prepared by the vapor deposition method, and the large cracks and defects in graphene are closed and filled by the interface polymerization technology. The nano atomic seawater desalination film has high selectivity and flux,can realize direct application in the field of concentration gradient film separation, and has a broad application prospect in the field of seawater desalination.
