Abstract:
1. A method of making a functionalized graphitic structure, comprising the actions of: a. exposing a portion of a multi-layered graphene surface extending from a silicon carbide substrate to an acidic environment so as to separate graphene layers in a portion of the multi-layered graphene surface; b. exposing the portion of the multi-layered graphene surface to a functionalizing material that binds to carbon atoms in the graphene sheets so that the functionalizing material remains between the graphene sheets, thereby generating a functionalized graphitic structure; c. drying the functionalized graphitic structure in an inert environment; d. subjecting a portion of the functionalized graphitic structure to a reducing environment; and e. applying a second masking material that resists the reducing environment to a portion of the functionalized graphitic structure prior to the action of subjecting the portion of the functionalized graphitic structure to the reducing environment.
