▎ 摘  要

NOVELTY - Graphene composite modified activated carbon material comprises 1-50 pts. wt. graphite oxide, 0.1-5 pts. wt. microwave inducer, 0.9-53 pts. wt. high molecular material, 10-200 pts. wt. activated carbon and 950-999 pts. wt. water. USE - The material is useful in an air purification material (claimed). ADVANTAGE - The carbon material: has high specific surface area (31% higher than that of the activated carbon) and high adsorption capacity; can absorb formaldehyde and other pollutants in the air; can have uniformly expanded and stably coated graphene on the surface of the graphene composite modified activated carbon material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene composite modified activated carbon material comprising (1) mixing the graphite oxide, microwave inducer, high molecular material and water to obtain the graphite oxide mixed solution, (2) dipping the activated carbon in the graphite oxide mixed solution to obtain the graphene modified activated carbon composite material and (3) subjecting the graphite oxide modified activated carbon composite material to a microwave puffing reaction to obtain the graphene composite modified activated carbon material. DESCRIPTION OF DRAWING(S) - The drawing shows a process flow diagram of the graphene composite modified active carbon material. (Drawing includes non-English language text).
