NOVELTY - Preparation of graphene desalination film involves adding nano-graphene oxide to casting solution to obtain base film by liquid-solid phase conversion method, adding diaminotoluene, dehydrated pear and organic phase of cyclopentane trichloride, subjecting base film to interfacial polymerization to form polyamide functional layer in the organic phase of propylenediamine aqueous phase and cyclopentane chloride, heat-treating, oxidizing, washing and drying. USE - Preparation of graphene desalination film. ADVANTAGE - The method enables simple preparation of graphene desalination film.
