Abstract
[EN] A systematic characterisation of single wall carbon nanotubes (SWCNTs) material after successive purification steps, including reflux treatment with nitric acid, air-oxidation and annealing, has been performed. During the nitric acid reflux treatment, micro Raman spectroscopy further proves that the SWCNTs diameter distribution can be selectively tuned towards smaller tubes. On the other hand, the subsequent oxidation/ annealing processes lead to samples preferentially containing larger tube diameter. These findings are further underlined by transmission electron microscopy. The applied purification process efficiently removes the undesired species of metal...
