▎ 摘  要

NOVELTY - Improving oxidation graphene material compatibility with polycarbonate by modified method, comprises (i) dispersing the graphene oxide in 50% aqueous ethanol solution to obtain first suspension, (ii) adding modifier into the first suspension and heating after finishing the reaction to obtain second suspension, (iii) washing the second suspension with deionized water and centrifuging to obtain a precipitate, and (iv) vacuum drying the precipitate under the condition of constant temperature to obtain modified graphene oxide, where the modifier is mixture of carbonyldiimidazole, phenol and sodium bicarbonate. USE - The method is useful for improving oxidation graphene material compatibility with polycarbonate by modified method.
