Abstract: Carbon nanotubes can vertically grow in the nanopores of AAO template. However, when out nanopores, carbon nanotubes are no longer aligned and become bended, and their film surface is not even. So, their application is heavily limited. In order to get aligned carbon film with even surface, the carbon nanotube film was switched the bottom and top by transferring them to other substrate. The even surface that can provide working surface in the application of carbon nanotube film was obtained by disposal of aluminum and alumina oxide gradually. The disposal results of alumina by 5% NaOH and 6%H3PO4＋1.8%H2CrO4 were compared

Key words: AAO template, Carbon nanotubes, Aligned carbon nanotubes film, Even surface
