Abstract

The present invention is related to a method for producing functionalised short carbon nanotubes with at least one open tip by mechanical treatment of long carbon nanotubes, wherein said long nanotubes are submitted to mechanical milling forces in the presence of a reactant able to chemically react with the nanotubes so that short carbon nanotubes comprising at least one specific chemical group are obtained.
