▎ 摘  要

NOVELTY - A graphene-melamine foam aerogel is black, and has a density of 8-15 mg/cm3 and a specific surface area of 100-500 m2/g. USE - Graphene-melamine foam aerogel is used for absorbing organic pollutants in water. ADVANTAGE - The graphene-melamine foam aerogel comprises a super-hydrophilic melamine foam as skeletal structure, can be easily immersed in water, quickly absorbs organic pollutants in water, and has excellent compression performance and recyclability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-melamine foam aerogel, which involves mixing graphene oxide with deionized water, ultrasonically dispersing for 1-5 hours to obtain 1-4 mg/mL graphene oxide aqueous solution, adding a reducing agent to obtain a mixed liquid, adding washed melamine foam, hydrothermally reacting at 70-180 degrees C for 2-20 hours to obtain a graphene-melamine foam hydrogel, cleaning the hydrogel with a solvent for 24-48 hours, and freeze-drying at -70 degrees C to -50 degrees C for 24-72 hours. The mass ratio of reducing agent and graphene oxide is 0.07-1:11.
