The Effect of Ultrasonic Treatment on the Morphology and Microstructure of TiO₂ Nanotubes Prepared by DC Anodization

Abstract:

This paper presents the effect of ultrasonic treatment on the morphology and microstructure of TiO₂ nanotubes prepared by DC anodization method. The TiO₂ nanotubes were grown by one-face anodization at room temperature on titanium sheets of 0.25 mm thickness and 99.7% purity. The electrolyte was composed of ethylene glycol (EG), ammonium fluoride (0.3% wt NH₄F) and deionized water (2% V H₂O). A constant DC voltage of 50 V was applied during anodization for 2 hours. The samples were ultrasonically cleansed in ethanol for different extended periods of time: 0, 10, 30 and 50 minutes respectively. The samples were annealed at 450 °C for 2 hours. The surface morphology and microstructure of the TiO₂ nanotubes formed were studied by XRD and SEM. The best result was obtained when the sampleswere ultrasonicated for 30 minutes.
