▎ 摘 要
NOVELTY - Carbon alkyl chain modified graphene comprises alkyl chain modified graphene layer containing an alkyl chain, where the alkyl chain modified graphene is modified by reducing graphene oxide to obtain the product. USE - The carbon alkyl chain modified graphene film is useful in separating water-in-oil mixture, water and alcohol immiscible liquid and sewage treatment (claimed). ADVANTAGE - The film increases alkyl chain length; is suitable for industrial separation, simple and easy to use; and has strong practicability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for (1) carbon alkyl chain modified graphene film made of alkyl-chain-modified graphene; (2) preparing carbon alkyl chain modified graphene comprising subjecting graphene oxide to reduction and modification with alkylamine as reducing agent, to obtain carbon chain alkyl modified graphene, where the carbon alkyl chain-modified graphene layer comprises an alkyl chain; and (3) preparing carbon alkyl chain modified graphene film comprising reducing and modifying the graphene oxide with alkylamine as the reducing agent, to obtain carbon alkyl chain modified graphene, dispersing the carbon alkyl chain modified graphene in the organic solvent and filtering.
