▎ 摘  要

NOVELTY - Preparing organic functionalized graphene oxide comprises (i) dispersing graphene oxide in distilled water under ultrasonic conditions to prepare a graphene oxide solution; (ii) adding organic functional reagent into graphene oxide solution and heating to react in a water bath to obtain organic functional graphene oxide solution; and (iii) washing solution obtained in step (ii) centrifugally and freeze-drying. USE - The method is useful for preparing organic functionalized graphene oxide. ADVANTAGE - The method: produces graphene oxide with expanded the interlayer distance which is beneficial to the occurrence of interlayer reactions of the graphene composite material and has excellent lipophilicity and good compatibility with polyester matrix; utilizes mature and readily available raw materials; and is simple, safe and is conducive to large-scale synthesis.
