Abstract

Disclosed is a method for producing edge-functionalized graphite or graphene with fluoro groups. According to the method, graphite is pulverized into smaller pieces and is then allowed to react with a surrounding material containing fluorine or a fluorocarbon compound. The method enables the production of graphite or graphene functionalized with fluoro groups, which could not be achieved by conventional mechanochemical methods. In addition, the method is carried out in a very simple and economical manner and is suitable for large-scale production.
