Abstract

In this study Titania nanotube arrays were prepared at room temperature (~25 ºC)
via electrochemical anodization process of pure titanium foil in glycerol base
electrolyte, different concentrations of ammonium fluoride salt (0.5 and 1.5wt.%)
were added to the electrolyte as a tube enhancing agent. When anodizing Ti in 0.5
wt. % NH4F, nanotubes are formed with 54 ± 10 nm tube diameter, 20 ± 3 nm wall
thickness and 1.76 <m tube length. When anodizing Ti in 1.5 wt. % NH4F,
nanotubes are formed with 69 ± 10 nm tube diameter, 29 ± 3 nm wall thickness and
2.71 <m tube length. The morphology and structure of the Titania films were studied
by scanning electron microscopy (SEM), X-ray diffraction (XRD), and atomic force
microscopy (AFM).
