NOVELTY - Preparing aminated graphene oxide, comprises (i) weighing graphite flakes, and passing graphite flake by improved Hummers method to obtain graphene oxide dispersion liquid, (ii) crushing the obtained graphene oxide dispersion by cell crushing instrument for 15-60 minutes, then ultrasonicating for 1-2 hours, freezing and drying to obtain graphene oxide powder, (iii) adding the obtained graphene oxide powder to organic solvent, ultrasonicating for 30 minutes, then adding small molecular amine compound and dehydrating condensing agent, adding into distillation flask, and refluxing for 12-24 hours to obtain condensed product, and (iv) washing the product using deionized water, then reacting at 120-130 degrees C in the constant-temperature oil bath, centrifuging through centrifuge and filtering to obtain aminated graphene oxide sheet with different sizes of the dispersion, freezing and drying to obtain aminated graphene oxide powder. USE - The method is useful for preparing aminated graphene oxide.
