In this study, titanium oxide nanotubes anodized on threedifferent surface morphologies of titanium foils, were investigated. AFM imagesis used to show different surface roughness of these foils. Nanotubes wereanodized on titanium foils with ۱) no polishing process (A sample), ۲)electropolishing process (B sample) and ۳) electropolishing process in ethanolicelectrolyte (C sample). To study the ordering of titanium oxide nanotubes, theFE-SEM images of nanotubes backside were investigated. It can be seen that bydecreasing surface roughness, the distribution of nanotubes diameter sizebecomes more uniform significantly and thereby highly ordering of nanotubescan be observed.
