Abstract :

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.
