US Patent 7252884 - Porous carbon with carbon nanotube dispersion


This patent from NASA deals with an improved hydrogen storage material with more uniform porosity and improved strength by dispersing carbon nanotubes into a porous carbon matrix. Claim 1 reads:

1. A three-dimensional structure comprising solid carbon having carbon nanotubes (CNTs) dispersed therein, said solid carbon with said CNTs dispersed therein being formed about three-dimensionally ordered spherical voids arranged in an opal-like lattice, said solid carbon being generated by carbonization of a carbon yield material having said CNTs dispersed therein.
