Abstract:

The study describes the interference color of anodic TiO2 nanotube arrays on titanium
foil. TiO2 nanotube arrays are prepared by oxidizing titanium foil in an aqueous electrolyte solution
of hydrofluoric acid (HF, 0.5 wt.%). The morphologies of the oxide film are characterized by
FESEM. The empirical color properties are obtained using the L*a*b* system. The different
interference colors of oxidized Ti samples are obtained depending on the anodization time. The
anodization time clearly indicates a strong effect on the reflectance at the visible wavelength region,
thus confirming the observed color differences. Consequently, the interference colors can be
controlled by the anodization time. By observing the coloration of Ti during the anodization, the
interference colors can be utilized to identify the thickness of oxide layer and the formation of
nanotubes on Ti sheet.
