▎ 摘　　要

NOVELTY - Preparing branched-chain fatty acid modified superhydrophobic graphene oxide, comprises dispersing graphene oxide in a reaction solvent, adding branched-chain fatty acid, reacting at 110-150 degrees C for 8-24 hours under reflux condition, then cooling to room temperature, centrifuging for 30 minutes, washing the resulting precipitate with methanol, ethanol and isopropanol respectively, continuing centrifuging, removing the supernatant, and drying the resulting solid at 80 degrees C for 24 hours. USE - The method is useful for preparing branched-chain fatty acid modified superhydrophobic graphene oxide (claimed). ADVANTAGE - The method: has simple process and low cost; does not utilize high-pollution chemical solvents; and is environmentally friendly, and suitable for industrial production.
