Abstract: 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.

Key words: carbon nanotube, AAO template, electrodeposited method
