Fabrication of TiO2 nanotubes (NTs) has extensive application properties due to their high corrosion resistant and compatibility with biomedical applications, the synthesis of TiO2 nanotubes over titanium has drawn interest in various fields. The synthesis of TiO2 NTs using novel in-situ step-up voltage conditions in the electrochemical anodization process is recorded in this work. For manufacturing the NTs at 1 hour of anodization, the input potential of 30, 40 and 50 V was selected. With increasing step-up voltage during the anodization process, an improvement in the NTs was observed, favoring corrosion resistance properties. The surface of NTs enhances the structure of the ribs, raising the potential for feedback over time. XRD was used to analyze phase changes, and HR-SEM analyzed surface topography. Impedance tests found that longer NTs improved the corrosion resistance.

Highly ordered closely packed TiO2 nanotubes were successfully fabricated by anodization of Ti foils in ethylene glycol-based electrolytes. For an identified electrolyte, the dependence manner of the nanotube dimension to the anodization parameters, including anodization voltage and time were systematically investigated. The inner diameter depends linearly on the anodization voltage but is time independent. The morphology of the tube is relative to the anodization voltage. The tube length is closely relative to the anodization time. Keeping the anodization voltage, the length will increase with the time rising to an extent and then maintain a relatively steady value. Longer nanotubes will be obtained when the anodization voltage is higher for a determined time. TiO2 nanotube-based dye-sensitized solar cells (DSSCs) were fabricated. The results showed that the conversion efficiency was related to the tube dimension. The optimum efficiency of 4.25% is obtained.

The geometry of self-organized TiO2nanotubes, obtained by electrochemical anodization, has been determined by using fuzzy reasoning approach. The efficiency of TiO2nanotubular layer in biomedical applications depends on geometry and available surface area of nanotubes, which can be determined by their diameter and length. The structure of nanotubes depends on processing parameters of electrochemical anodization, like applied potential, anodization time, and pH of electrolyte. A proposed method showed the possibility of estimation and optimization the nanotubular architecture on Ti and Ti alloys by choosing the appropriate processing parameters based on representative experimental data. A fuzzy reasoning approach was utilized by using Matlab Software.
