Abstract
A composite, comprising a binder, the binder comprising one or more of polymeric, metallic, or ceramic, or pyrolytic carbon binder and a nanostructured carbon having a cellular structure. The cellular structure comprises one or more cell walls having a structure formed by a template and one or more cavities. Each cavity is substantially enclosed by the one or more cell walls and substantially unimpregnated by a liquid or solid.

A composite, comprising:
- nanostructured carbon particles having a multicellular structure and a particle diameter of 1 mm or smaller, the multicellular structure comprising interconnected cell cavities, the cell cavities unfilled by a liquid or solid and enclosed by a network of bridged cell walls, the cell walls having a thickness of 100 nm or smaller and comprising sp2-hybridized carbon;
- and a polymeric binder material binding the nanostructured carbon particles, wherein the polymeric binder being a thermoplastic polymer comprising at least one of the following:
- poly(methyl methacrylate), acrylonitrile butadiene styrene, polyamide, polylactic acid, polybenzimidazole, polycarbonate, polyether sulfone, polyoxymethylene, polyether ether ketone, polyetherimide, polyethylene, polyphenylene oxide, polphenylene sulfide, polypropylene, polystyrene, polyvinyl chloride, polytetrafluoroethylene, or copolymers thereof;
- and a composite density that is less than a density of the polymeric binder material.
