Exfoliation of Single-Walled Carbon Nanotubes by Electrochemical Treatment in a Nitric Acid

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 electrode...

Summary: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.
