Method for the production of functionalised short carbon nanotubes and functionalised short carbon nanotubes obtainable by said method

摘要

The present invention is related to a method for producing short carbon nanotubes with open tips by mechanical treatment of long carbon nanotubes, characterised in that it comprises the step of submitting said long nanotubes to mechanical milling forces. The present invention is also related to a mixture comprising long nanotubes and at least 10% of short carbon nanotubes, said short carbon nanotubes having at least one open tip and having an average length smaller than 2 mu m.
