▎ 摘　　要

NOVELTY - Preparing fluorinated graphene dispersion in large quantities involves mixing fluorinated graphite and ionic liquid at mass ratio of 1:(1-5) into deionized water, ultrasonically uniform. The mixture is placed in reaction kettle and heated at 150-250 degrees C for 12-24 hours to obtain black mixed solution. The mixed solution is centrifuged, collected upper layer dispersion. The deionized water is added and sonicated to continue centrifugation. The ultrasonic water is added uniformly with deionized water, centrifuged 5-10 times to obtain fluorinated graphene dispersion. USE - Method for preparing fluorinated graphene dispersion in large quantities. ADVANTAGE - The method enables to prepare fluorinated graphene dispersion in large quantities that is green and environmentally friendly, has simple preparation process, and low production cost.
