▎ 摘　　要

NOVELTY - Preparing graphene-aluminum base layer assembled water and seawater desalination device function area involves dispersing the graphene oxide material at gas-liquid interface, self-assembling into a graphene oxide film, and placing the flexible substrate on the bottom of the container with upper electrode and lower electrode facing upward on the flexible substrate, extracting aqueous solution to deposit graphene oxide film on the substrate. The aluminum particles are dispersed in the solvent, coated the surface of the graphene oxide film, and dried, repeated multiple times. The graphene oxide film and aluminum particle layer are arranged alternately, and graphene oxide-aluminum coating is obtained after drying. The graphene oxide is reduced by microwave method to obtain functional area of graphene-aluminum-based water desalination and seawater desalination device. USE - Method for preparing graphene-aluminum base layer assembled water and seawater desalination device function area. ADVANTAGE - The method enables to prepare graphene-aluminum base layer assembled water and seawater desalination device function area that achieves faster evaporation effect, increases output power and fresh water output.
