Preparation and Characterization of Micro-Nanostructured Anatase Film

Abstract:

Micro-nano structured TiO₂ films were prepared by hydrothermally seed layer-induced synthesis. The results showed that the films were composed of TiO₂ platelets in size of 2μm~10μm. The maximum distance between platelets was ~4 μm. There were TiO₂ nanodots (seed layer) in size of ~100nm between TiO₂ platelets. This structured film was proven to be anatase and more anatase was detected along with hydrothermal synthesis. Water contact angle varied from 103° to 149° along with hydrothermal synthesis and all films showed super-hydrophilicity after UV illumination. These micro-nano structured films obtained in this study could potentially applied in many biomedical applications, e.g., osseointegration film and cell sheet technology, owing to its excellent biocompatibility and UV switchable super-hydrophilicity.
