Production of Bamboo-shape Carbon Nanotubes Film with Uniform Diameter Distribution and Its Characterizations

the AAO template was produced with one step anodizing oxidation, the pores were not well arrayed in order, but they were distributed on substrate almost in proportional spacing, they effectively increased the surface area and provided depositing sites for catalysts. Cobalt particles were uniformly electrodeposited on this AAO template, the cobalt particles had uniform diameter. CVD were used to grow carbon nanotubes on this template. The investigation of SEM and TEM showed that carbon nanotubes in high density uniformly covered the surface of the template and formed a film. These carbon nanotubes had the single shape of bamboo. The growth mechanism of these carbon nanotubes with bamboo shape was proposed on the basis of growth dynamics.
