Abstract
Using SWNT-CA as scaffolds to fabricate stiff, highly conductive polymer (PDMS) composites. The SWNT-CA is immersing in a polymer resin to produce a SWNT-CA infiltrated with a polymer resin. The SWNT-CA infiltrated with a polymer resin is cured to produce the stiff and electrically conductive composite of carbon nanotube aerogel and polymer.
Claims9
A mechanically stiff, electrically conductive composite comprising:
- a porous carbon material having 5 to 95% by weight carbon nanotubes and 5 to 95% carbon binder, and a polymer infiltrated within said porous carbon material, wherein the porous carbon material comprises a carbon aerogel monolith comprising bundles of single-walled carbon nanotubes (SWNTs) covalently crosslinked by carbon nanoparticles obtained by organic sol-gel reaction, wherein the carbon aerogel monolith comprises at least 20 wt. % of SWNTs, and wherein the composite has an electrical conductivity of 10 S/m or more.
