摘要
Single-walled carbon nanotube (SWNT) bundles have been dispersed by an electrolysis method. Intercalation of bundles by NO3 widens locally the inter-tube spacing. Bundles are nanodispersed into individual nanotubes after deintercalation (see Figure). This method could be used to fabricate electrodes for high-capacity batteries and supercapacitors.
