▎ 摘　　要

NOVELTY - Naphthyl highly reactive graphene dispersant (IV) is new. USE - (IV) is useful in preparing graphene dispersion liquid (claimed). ADVANTAGE - (IV): uses naphthalene diamine, which can be closely combined with graphene through π-π interaction; uses silanol, which can make the dispersant soluble in water and other polar solvents; have self-crosslinking reactivity; uses small amount of dispersant, and graphene can be dispersed in high concentration in polar organic solvents i.e. water and ethanol, and the dispersant canserve as highly reactive site to combine graphene with other materials and thus has broad application prospects. DETAILED DESCRIPTION - Naphthyl highly reactive graphene dispersant of formula (IV) is new. INDEPENDENT CLAIMS are also included for: Preparation of (IV); and Use method of naphthyl highly reactive graphene dispersant (IV) in preparing graphene dispersion liquid, comprising adding graphene powder into the aqueous solution or alcohol solution of the naphthyl highly reactive graphene dispersant, performing preliminary dispersion through ultrasonic treatment, and then ultrasonically treating with an ultrasonic cell pulverizer to obtain graphene dispersion.
