▎ 摘　　要

NOVELTY - Preparing graphene/epoxy resin composite material comprises (i) pre-soaking graphene in absolute ethanol, (ii) adding alkyl benzene sulfonate, graphite and epoxy resin in anhydrous ethanol and stirring uniformly using a planetary stirring and ultrasonic stirrer to obtain mixed solution, then adding in a vacuum drying box and drying to remove anhydrous ethanol, and (iii) adding curing agent in the mixed solution, and curing to obtain final product. USE - The method is useful for preparing graphene/epoxy resin composite material. ADVANTAGE - The composite material has excellent dispersibility, low cost, simple preparation method and low technical requirement.
