Isolation of single-walled carbon nanotubes from double and multi-walled carbon nanotubes

摘要: A method and system are disclosed for separating single-walled carbon nanotubes from double multi-walled by using the difference in buoyant density of Single-Walled versus Multi-Walled nanotubes. In one embodiment, comprises providing a vessel with first second solutions. The solution quantity nanotubes, including single walled have density, having density. has third between said densities. is centrifuged to faun layers vessel, layers. predominantly layer, layer.
