▎ 摘 要
NOVELTY - A mercapto-modified graphene oxide comprises mercapto group grafted on graphene oxide sheet. USE - Mercapto-modified graphene oxide (claimed). ADVANTAGE - The mercapto-modified graphene oxide is manufactured by simple process with reduced energy consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of mercapto-modified graphene oxide, which involves using dimethylformamide, water, dimethyl sulfoxide, dimethylacrylamide or N-methylpyrrolidone as solvent, graphene solution, triethylamine, thiocarboxylate salt and thio-carboxylic acid.
