Abstract

A method to make free-standing graphene sheets and the free-standing graphene sheets so formed. The method includes the steps of exfoliating partially oxidized graphene from a carbon-containing electrode into an aqueous solution, acidifying the aqueous solution, and separating from the acidified solution partially oxidized graphene sheet. The partially oxidized graphene is then dried to yield free-standing graphene sheet having a carbon-to-oxygen ratio of at least about 8.0.
