▎ 摘  要

NOVELTY - An edge-functionalized graphene is prepared by reacting an organic material having a functional group with graphite in a reaction medium containing methanesulfonic acid and phosphorus pentoxide, or a reaction medium containing trifluoromethanesulfonic acid, and substituting bonds of edge positions between graphene with covalent bonds between graphene and the organic material. The functional group is carboxylic acid group, amide group, sulfonic acid group, carbonyl chloride group, or carbonyl bromide group. USE - Edge-functionalized graphene (claimed). ADVANTAGE - The edge-functionalized graphene is manufactured economically with improved productivity, and with reduced damage of graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the edge-functionalized graphene.
