Abstract: Carbon nanotube bundle arrays were successfully grown on titanium plate,which was anodized for 4 minutes,by thermal chemical vapor deposition.The images of scanning electron microscopy and transmission electron microscopy revealed that the morphology of carbon nanotubes was aligned bundles and the bundle was composed of tangled carbon nanotubes.The current-voltage curve was measured by a micromanipulator manual probe station,the result indicated there was an ohmic contact between titanium substrate and carbon nanotube.A TiC layer between titanium substrate and carbon nanotube is the reason of the ohmic contact,which could be ascertained by X-ray diffraction（XRD） and titanium-carbon binary phase diagram.The analysis of cyclic voltammetry and AC impedance testified the excellent capacitive character of this material.
