Abstract

The application discloses methods of fabricating three-dimensional (3D) graphene crystalline foam, based on mixing a carbon source with a skelet (scaffold) powder. In one embodiment heat and pressure are used to compact the carbon and a metal powder into a close packed structure. In another embodiment a 3D crystalline graphene foam is fabricated with a large surface area (550 m/g) from a 3D metal foam, depositing a layer of graphene using chemical vapor deposition (CVD), depositing a polymer support and removing the metal via wet chemical etching, such that the graphene retains the configuration, and then finally removing the polymer. A method of fabricating the metal foam framework and coating the metal with graphene are also disclosed.
