Synthesys of nanostructured TiO2 films by the method of anodic oxidation		  pdf 

ABSTRACT

The method of synthesys of TiO2 nanoporous layers on the surface of titanium substrate employing an anodization technique is described and results of study of their physical properties was presented. Characterization of the layer using XRD, Raman spectroscopy, the both SEM and AFM imaging allowed to investigate the effect of thermal processing on both the structure of layers and the size of crystallites in them. AFM images indicate that the surface of the layers is sufficiently brittle, while SEM images demonstrate the nanoporous structure with the pore diameter of 10-20 nm. After oxidation, the layers were partially in the amorphous phase, whereas after the annealing in air at 300-500°C temperatures they are obtained a polycrystalline structure. After annealing at 300°C, the size of TiO2 crystallites is 5-6 nm, and after annealing at 500°C, they increase and reach 10 nm.
