▎ 摘  要

NOVELTY - A fluorinated graphene compound is prepared by mixing nano sol and nanographite-reinforced carbon, completely drying, pulverizing into fine powder, adding nano-graphite carbon mineral complex fluoride agent, reacting, soaking in hydrochloric acid and sulfuric acid, washing water with high purity, vacuum drying, grinding into powder, adding organic solvent, adding grinding balls, mixing, ultrasonically treating, and centrifuging. USE - Method for preparing fluorinated graphene compound (claimed). ADVANTAGE - The raw materials are stable, and low-cost. The method is simple, low-cost, and suitable for industrial production. DETAILED DESCRIPTION - A fluorinated graphene compound is prepared by mixing nano sol and 2-3 wt.% nanographite-reinforced carbon at mass ratio of 50:1, completely drying at 65-70 degrees C, pulverizing into fine powder, adding nano-graphite carbon mineral complex fluoride agent, reacting at heating rate of 10 degrees C/minute to 500-550 degrees C for 2-3 hours under 0.5-1 MPa pressure and high purity nitrogen gas, soaking in hydrochloric acid and sulfuric acid at molar ratio of 1:3, washing water with high purity, vacuum drying, grinding into powder having particle size of 80-90 mesh, adding 80 mg/mL organic solvent to obtain suspension, adding grinding balls, mixing for 3-4 hours, ultrasonically treating for 3-4 hours, and centrifuging at rate of 9000-10000 revolutions/minute for 50-60 minutes.
