QUALITATIVE AND QUANTITATIVE ANALYSIS OF DIFFERENT MORPHOLOGIES OF TIO2 NANOTUBES USING FE-SEM-EDS

We report the preparation of TiO2 nanotubes by anodisation method in which the inner diameter vary depending on the distance between the anodisation electrodes. Nanotubes create by different anodisation distance between the electrodes have different inner and outer diameter that means they have different morphologies. A field emission scanning electron microscope FE- SEM was employed for the morphological characterization of TiO2 nanotubular layers however; FE- SEM -EDS was employed for the qualitative and quantitative analysis of nanotubes. The synthesised nanotubes were used to control the release kinetics of methylene blue in aqueous media. Methylene blue was used to simulate the drug. The results show the possibility of using the controlling drug release by control the inner and outer diameter of TiO2 nanotubes mouth.
