Claim:
1. A composite foam comprising: a metal template comprising a plurality of sintered interconnects, having a plurality of first non-spherical pores, a first non-spherical porosity, and a first surface-area-to-volume ratio, wherein the plurality of sintered interconnects comprises a plurality of dendritic particles; and a conformal atomic-scale film disposed directly over the metal template to form a 3-dimensional interconnected structure, having a plurality of second non-spherical pores, a second non-spherical porosity, and a second surface-area-to-volume ratio approximately equal to the first surface-area-to-volume ratio, wherein the 3-dimensional interconnected structure conforms to a profile of the plurality of sintered interconnects comprising the plurality of dendritic particles,wherein each dendritic particle comprises a plurality of branches,and wherein each branch comprises a plurality of ligaments; wherein the conformal atomic-scale film comprises at least one of a layer of graphene and a layer of hexagonal boron nitride.
