▎ 摘　　要

NOVELTY - Graphene dispersing system comprises 0.1-0.5 pts. wt. graphene, 1-3 pts. wt. 7-hydroxy-4 methylcoumarin, 1-5 pts. wt. polyvinyl alcohol, 90-120 pts. wt. alcohol diluent and 30-50 pts. wt. ether diluent. USE - Graphene dispersing system. ADVANTAGE - The graphene dispersing system improves the dispersibility of the graphene in the organic solvent and epoxy resin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene dispersing system, which involves: (A) adding graphene to alcohol diluent, and ultrasonically stirring uniformly to obtain a graphene dispersion; (B) mixing and stirring the remaining alcohol diluent and ether diluent, and then adding 7-hydroxy-4-methylcoumarin and polyvinyl alcohol, and stirring uniformly to obtain a diluent mixture; and (C) dispersing the graphene into the diluent mixture, stirring while dropping, and dispersing ultrasonically for more than 30 minutes.
