The paper is devoted to the electrochemical anodizing method for TiO2 nanotube layers generation on titanium surface. It is commonly accepted that parameters like anodizing time, electrical voltage and the actual type of electrolyte are important factors in what concerns the TiO2 nanotube diameters and their surface density. The present study considers self-organized titanium nanotubes resulted from an aqueous solution of 49.5 wt% H2O, 49.5 wt% glycerol, 1 wt% HF used as the electrolyte. The actual anodizing duration was 8 hours at an applied voltage of 25 V. Through the technique of scanning electron microscopy, it is shown that the resulted tubular nanostructure is one-dimensional having an approximate inner and outer diameters of 90 nm and 110 nm, respectively. From an electrical point of view, the analysed materials properties were determined using electrochemical and dielectric impedance spectroscopy tests.
