This is a false colored low magnification electron micrograph of free standing graphene foam. Graphene foam is made by growing a few layers of graphene on the surface of a porous metal foam skeleton using chemical vapour deposition technique. The metal foam skeleton is then removed by carefully dissolving it in an etching solution. Because of its unique properties, e.g. electrically conductive, highly porous, and lightweight, graphene foam has the potential to be used in numerous advanced applications including chemical sensing, energy storage, and ultra-lightweight structures.
