NOVELTY - Preparing graphene oxide-epoxy resin composite comprises mixing the graphene oxide and acetone, subjecting to ultrasonic treatment for 1 hour, pre-heating the epoxy resin under a water bath, adding the mixture of graphene oxide-acetone into preheated epoxy resin, stirring via magnetic stirrer for 0.5 hour in a fume hood, sonicating for 1 hour, placing the mixture in a vacuum box at 80 degrees C for 12 hours, adding a curing agent into a mixing system, stirring for 10-20 minutes, pouring the mixture into a preheated mold, curing at 60 degrees C for 2 hours, then taking out. USE - The method is useful for preparing graphene oxide-epoxy resin composite (claimed). ADVANTAGE - The method is simple.
