Patent number: 10014090Abstract: Disclosed here is a composition comprising at least one high-density carbon-nanotube-based monolith, said monolith comprising carbon nanotubes crosslinked by nanoparticles and having a density of at least 0.2 g/cm3. Also provided is a method for making the composition comprising: preparing a reaction mixture comprising a suspension and at least one catalyst, said suspension is a carbon nanotube suspension; curing the reaction mixture to produce a wet gel; drying the wet gel to produce a dry gel, said drying step is substantially free of supercritical drying and freeze drying; and pyrolyzing the dry gel to produce the composition comprising a high-density carbon-nanotube-based monolith. Exceptional combinations of properties are achieved including high conductive and mechanical properties.Type: GrantFiled: July 22, 2016Date of Patent: July 3, 2018Assignee: Lawrence Livermore National Security, LLCInventors: Marcus A. Worsley, Theodore F. Baumann, Juergen Biener, Supakit Charnvanichborikarn, Sergei Kucheyev, Elizabeth Montalvo, Swanee Shin, Elijah Tylski
