NOVELTY - Improving compatibility of graphene oxide with polyethersulfone material comprises (i) dispersing graphene oxide in 50% aqueous ethanol solution to obtain first suspension, (ii) adding modifier into first suspension, heating, completing the reaction to obtain second suspension, (iii) washing second suspension with de-ionized water, centrifuging and separating to obtain precipitate, and (iv) vacuum drying the precipitate under constant temperature to obtain modified graphene oxide, where the modifier is mixture of phenylbenzimidazole sulfonic acid, zinc dialkyl dithiophosphate, and diglyme. USE - The method is useful for improving compatibility of graphene oxide with polyethersulfone material. ADVANTAGE - The grafted graphene oxide has good compatibility with polyether sulfone groups. The method improves the compatibility between graphene oxide and polyether sulfone and suitable for large addition of graphene oxide in polyethersulfone.
