▎ 摘　　要

NOVELTY - The method involves adding fatty acid in the catalyst in the water solution of dicyclohexyl carbodiimide for activation. The aqueous solution containing graphene oxide is gradually added. The water bath is heated. The water bath is stirred. The centrifugal product is separated to obtain solid product. USE - Preparation method for graphene modified material of air filter sponge (all claimed). ADVANTAGE - The graphene-modified material is effectively fixed. Th odor in the air is reduced. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a graphene modified material; and (2) an air filter sponge. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation illustrating the infrared spectrum of the graphene-modified material. (Drawing includes non-English language text)
