ABSTRACT: This paper reports the structural properties of the high-pressure and high-temperature (HPHT) treated double-walled carbon nanotubes (DWCNTs) based on Raman, XRD and TEM experiments. It was found that the DWCNTs are more stable toward HPHT treatment than the single-walled carbon nanotubes (SWCNTs). We propose that this is probably because the DWCNTs tend not to be deformed by compression and thereby they are less reactive under pressure compared to SWCNTs.
