▎ 摘　　要

NOVELTY - The method involves pouring the graphene powder into liquid to mix to obtain the first mixed solution. The ball milling ultrasonic treatment for the first mixed solution is performed for more than three times to obtain a second mixed solution. The second mixed solution is deposited and layered to take portion of the upper layer liquid as the third mixed solution. The ball milling ultrasonic treatment to the third mixed solution is performed more than one time to obtain graphene dispersion liquid. The ball milling ultrasonic treatment is performed to add grinding ball to the mixed solution for grinding and performing ultrasonic treatment to the mixed solution. USE - Method for dispersing graphene in graphene distribution liquid such as lubricating oil (all claimed) and water in liquid system. ADVANTAGE - The dispersion method improves the dispersibility of the graphene in the liquid system without introducing other chemical substances. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene distribution liquid. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene dispersion liquid.
