NOVELTY - Modified graphene oxide material preparation involves adding graphite powder to the mixed acid solution with stirring to obtain a suspension, placing the prepared suspension in a parallel electric field after adding potassium permanganate powder with stirring to obtain another suspension. The obtained suspension is cooled at room temperature, and then mixed with hydrogen peroxide solution and hydrochloric acid solution to obtain a third suspension. The obtained third suspension is washed with deionized water, filtered, and then added to 50% aqueous solution of ethanol to disperse to obtain a fourth suspension. A modifier is added to the obtained fourth suspension under heating for obtaining a fifth suspension. USE - Method for preparing modified graphene oxide material for a polyphenylene sulfide material (claimed). ADVANTAGE - The method prepares the modified graphene oxide material in a simple, cost-effective and eco-friendly manner. DETAILED DESCRIPTION - The fifth suspension is washed with deionized water and centrifuging to obtain a precipitate, where the precipitate is vacuum dried under constant temperature conditions to obtain modified graphene oxide for polyphenylene sulfide material. The mixed acid solution is prepared by mixing a sulfuric acid solution and nitric acid solution. The modifier is a mixture of sulfonic acid imidazole, phenol and zinc dialkyl dithiophosphate.
