Mega-Pore Nano-Structured Carbon
Applicant's present invention comprises a method for fabricating porous carbon materials having highly ordered nanostructures comprising the steps of first, forming a precursor solution comprising a block copolymer template and a carbon precursor; second, forming a self-assembled nanostructured material from the precursor solution; third annealing the nanostructured material thereby forming a highly ordered nanostructured material; fourth, polymerizing the carbon precursor to cure the nanostructured material; and pyrolyzing the nanostructured material wherein the block copolymer template is decomposed to generate ordered carbon nanopores and the nanostructured material is carbonized to form the walls of the carbon nanopores thereby forming a porous carbon material having a highly ordered nanostructure. In addition, the present invention further comprises a porous carbon material comprising a carbon nanostructure having ordered carbon nanopores that have uniform pore sizes ranging from about 4.5 nm up to about 100 nm.
