A method for characterizing carbon nanotubes.
High-resolution transmission electron microscopy and electron energy-loss spectroscopy of a multi-walled carbon nanotube (MWCNT) at elevated temperatures were studied. Although the observation was carried out at 200 kV, the crystal structures of the MWCNT were observed without introducing defects. In addition, contamination on the MWCNT, such as nanobubbles, was removed during the observation at 600 degrees C. In this paper, we report the observation conditions and experimental results. The experimental results obtained both at 600 degrees C and at room temperature were compared.
