▎ 摘　　要

NOVELTY - Preparing water-dispersible fluorinated graphene involves dispersing graphene oxide in deionized water to form a graphene oxide solution, adding hydrofluoric acid and concentrated nitric acid to the graphene oxide solution, shaking on bed for 5-15 minutes, performing the reaction at a temperature of 120-200 degrees C for 10-25 hours, every 0.5-1.5 hours during the reaction, and shaking on bed for 5-15 minutes. The reaction solution is centrifuged, washed, and dried to obtain final product. USE - Method for preparing water-dispersible fluorinated graphene. ADVANTAGE - The method enables to prepare water-dispersible fluorinated graphene which has high grafting rate and good dispersibility in water.
