NOVELTY - A water-soluble functionalized graphene is prepared by, at room temperature, immersing fluorinated graphite in alkali and strongly polar solvent to give first mixture, milling, transferring milled slurry-like mixture to second strongly polar solvent, sonicating, and drying. The fluorinated graphite and fluorocarbon is at a molar ratio of 0.5-1.1. The base is an alkali (earth) metal sulfide or alkali (earth) metal amide. The first or second strongly polar solvent comprises N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide or N-methylpyrrolidone. USE - Method for preparing water-soluble functionalized graphene (claimed). ADVANTAGE - The method is simple. It has high safety, less waste product, and is suitable for industrial production.
