摘要：
Oxidation of single wall carbon nanotubes using H2O2 is a common purification and tube opening procedure. We studied the effect of oxidation in well controlled conditions on SWNT samples with different mean diameters, prepared by laser-ablation, CVD and the HiPco process. Detailed multifrequency Raman spectroscopy evidences that oxidation damage depends strongly on the mean tube diameter, damage occuring to small tubes first and successively for larger diameter tubes. We use the peapod filling of the above samples as a control to what extent the tubes are open to the C-60 molecules.
