Abstract: Two types of coatings were prepared on the surface of aligned carbon nanotubes on AAO(Aluminum anodic oxide)template, CuPc coating by vacuum thermal deposition and cobalt coating by electrodeposition. Observations by SEM and TEM show that organic and inorganic coatings are obtained on the aligned carbon nanotubes. There is still a little difference between them: the back surface of carbon nanotubes has no film with the vacuum thermal deposition while the whole surface of nanotubes is coated with the electrodeposition method.
