An ordered open-cellular carbon microstructure and a methods for forming the ordered open-cellular carbon microstructure capable of greatly improving the carbon yield (remaining mass % after carbonization) of an open-cellular polymer material. In one embodiment, the method starts with providing an ordered open-cellular polymer template material. The polymer template material is immersed in a reservoir containing a liquid monomer solution, wherein the liquid monomer solution swells the polymer material. Then the polymer template material is removed from the reservoir containing liquid monomer solution. Excess liquid monomer solution is removed from the polymer template material. The liquid monomer solution absorbed into the polymer template material is polymerized forming a copolymer material by irradiating the template material with ultraviolet (UV) light in a nitrogen environment. The copolymer material is heated in an inert atmosphere, wherein the copolymer material is carbonized resulting in the ordered open-cellular carbon microstructure.
