Abstract:

The synthesis and the structure of graphitic nanotubes and buckybundles were studied by DC arc- discharge method and high resolution electron microscope respectively. The nanotubes are concentric tubings, 0.34nm between the consecutive carbon-layers in the nanotube walls and closed at the ends. The single-layered nanotubes, graphitic onion and the onion-shaped structure encapsulated with crystal nuclei were also observed. The microscopic structure of buckybundles is the same as that of nanotubes. Micrograph shows that the buckybundles are whiskers 0.2-0.6mm in diameter and 3-8mm in length, and orient in the direction of the electric field. The formation of buckybundles is supposed to be induced by crystal nuclei due to the presence of impurities in the doped graphitic rods.
