This thesis describes the synthesis of self-organized titanium dioxide nanotube layers by an electrochemical anodization of Ti at different conditions (time, voltage, concentration of NH4F in electrolyte with glycerol, conductivity and water content) at room temperature (~25ºC)were investigated.
In the current study, self-organized, vertically-oriented TiO2 nanotubes were successfully prepared by anodization method of a pure Titanium sheet (99.5%) usinganodization cell is designed for first time in Iraq (Homemade) from Teflon material according to our knowledge to produce self-ordered Titanium nanotube in organic based electrolytes (glycerol based electrolyte) an electrolyte solution containing (0.5, 1, 1.5 and 2 wt.% NH4F) then added water (2 and 5Wt.% H2O) to (0.5wt.% NH4F) only with 15V.The range of anodizing time and potential were between 1-4hr.
and 5-40V, where Wt.% represent weight percentage.
Scanning electron microscopy (SEM), Atomic force microscopy (AFM) and (XRD) X-Ray diffraction were employed to characterize the morphology and structure of the obtained Titania templates, optical interferometer (Fizeau frings) method to tubes length measurement.
For TiO2nanotubes fabricated in non-aqueous electrolyte, the influence of the NH4F concentration on characteristics of nanotubes was studied.
The results showed that when the NH4F concentration increased from 0.5 to 2wt.%NH4F, the tubes diameter, tubes length and roughness of TiO2 surface increased.
Also the effects of the anodizing time and anodizing potential were studied.
The formation of TiO2 nanotubes was very sensitive to the Abstract VII anodizing time.
Length of the tube increases with increasing anodizing time and anodizing potential significantly.
Either water content (2 and 5wt.%) with 0.5wt.% NH4F and the conductivity of electrolyte it is increasing the diameter, tube length and roughness of TiO2 surface increased, but simple increasing and formation of less homogenized TiO2 nanotube.
The optimal conditions for TiO2 formation was found 15V at 4hr with 0.5wt.% NH4F due to we obtain on best results for tube diameter, tube wall thickness, tube length and more homogenized of TiO2 nanotubes.
