In this study, titanium oxide nanotubes anodized on three different surface morphologies of titanium foils, were investigated. AFM images is used to show different surface roughness of these foils. Nanotubes were anodized on titanium foils with 1) no polishing process (A sample), 2) electropolishing process (B sample) and 3) electropolishing process in ethanolic electrolyte (C sample). To study the ordering of titanium oxide nanotubes, the FE-SEM images of nanotubes backside were investigated. It can be seen that by decreasing surface roughness, the distribution of nanotubes diameter size becomes more uniform significantly and thereby highly ordering of nanotubes can be observed.
