▎ 摘  要

NOVELTY - Preparing carboxylated graphene comprises (i) preparing graphene oxide solution, and (ii) choosing 100 ml (2 mg/ml) graphene oxide solution, adding 1 g chloroacetic acid and 1.2 g sodium hydroxide, and placing it in water bath for 1 hour, stirring reaction for 24 hours, and then vacuum filtering mixture with vacuum filtration device, and washing with deionized water many times to obtain carboxylated graphene oxide solution, and drying in vacuum drying oven at 60 degrees C to obtain carboxylated graphene oxide. USE - The method is useful for preparing carboxylated graphene. ADVANTAGE - The method adopts ultrasonic treatment of graphene oxide solution and vacuum filter device to react with graphene oxide to prepare carboxylated graphene oxide. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of process flow chart for preparing carboxylated graphene. (Drawing includes non-English language text)
