Nanotubes promise improved flame-resistant coating. An easy-to-apply, NIST developed coating significantly reduces the flammability of foam used in furniture. The thin coating is deposited onto the surface of all the nooks and crannies of the porous foam (top), with heat-dissipating multi-walled carbon nanotubes (MWCNT) uniformly distributed throughout (bottom). Carbon nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. In particular, owing to their extraordinary thermal conductivity and mechanical and electrical properties, carbon nanotubes find applications as additives to various structural materials. Nanotubes are members of the fullerene structural family. Their name is derived from their long, hollow structure with the walls formed by one-atom-thick sheets of carbon, called graphene. Nanotubes are categorized as single-walled nanotubes (SWNTs) and multi-walled nanotubes (MWNTs).
