NOVELTY - Preparing a six-membered heterocyclic ring covalently modified graphene oxide/epoxy resin composite material comprises adding a six-membered heterocyclic ring-modified graphene oxide to acetone, ultrasonically dispersing to obtain a mixed solution, where the ratio graphene oxide covalently modified by the six-membered heterocyclic ring to acetone is (0.033-0.036 g): (10-15 ml), adding an epoxy resin to the mixed solution, ultrasonically dispersing, drying to obtain an epoxy resin mixture, where the ratio of the epoxy resin to graphene oxide covalently modified by six-membered heterocyclic ring is (33-36): (0.033-0.036), adding a curing agent to the epoxy resin mixture, stirring, drying to obtain an epoxy resin mixture and pouring the epoxy resin mixture containing curing agent into the preheating mold, vacuum drying, solidifying to obtain a six-membered heterocyclic ring covalently modified graphene oxide/epoxy resin composite material. USE - The method is useful for preparing a six-membered heterocyclic ring covalently modified graphene oxide/epoxy resin composite material. ADVANTAGE - The method solve the problems of graphene having poor dispersibility and epoxy resin having poor compatibility; is highly economical and has small amount of covalently modified graphene oxide in the composite material, which greatly reduces the cost.
