▎ 摘　　要

NOVELTY - The method involves placing a to-be coated substrate in a water bath (1) below a water surface. The graphene flakes are placed on the water surface. The molecules (5) that float on the water surface, are added. The graphene flakes are compressed into a densely packed layer (6). The substrate is positioned below the densely packed layer. The water level is lowered and raised in the water surface. The surfactants or lipids are used as molecules. The sodium dodecyl sulphate and oils are used as molecules. The graphene flakes are functionalized by mixing with a 1% sodium hydroxide solution. The ethanol is used as the solvent. The functionalized graphene flakes are added as a suspension. USE - Method for coating a substrate with graphene. ADVANTAGE - Demineralization of sea water, decontamination of water with heavy metals, anti-corrosion protection coat of the substrate is ensured. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a water bath. Water bath (1) Positioning table (4) Surfactant molecule (5) Densely packed layer (6) Convex surface (7)
