    In this study, TiO2 nanotube array was successfully synthesized by anodizing a Ti foil in a Fluoride containing electrolyte and obtained a relationship between nanotube parameters and synthesis process parameters. The studied anodization parameters were anodization voltage and time. Scanning electron microscopy was used to study the tube morphology. The diameters of synthesized nanotubes at different anodization conditions ranged from 28 nm to 90 nm while the tube lengths ranged from 2.5 μm to 15 μm. The obtained tube length and diameter values were statistically analyzed, which showed a strong relationship between process parameters and tube morphology. It was found that the tube diameter obeys the following relationship with process parameters. “Diameter = 1.109(Voltage) + 6.863(Time) + 0.284”. This study facilitates the researchers to tailor the structure of the TiO2 nanotube layer according to the properties required.
