TiO₂ nanotubes, formation and properties — •Ghicov Andrei, Schmuki Patrik, Macak Jan, and Kunze Julia — WW4- LKO, University of Erlangen-Nuremberg, Martensstr.7, D-91058 Erlange

Electrochemically grown TiO₂ nanotubes represent a combination between a structure with a high effective surface area with numerous functional properties. The material has an adjustable crystalline structure (amorphous /anatase /rutile) which makes the ordered nanotube layers a candidate for even wider applications in different fields. The presentation will show how TiO₂ nanotubes can be grown on titanium substrates and how their geometry can be adjusted in desired ways by anodization parameters. The surface structure and - area are a key factors for wetting [1], biomedical [2], catalytic [3] and electronic [4] applications - some specific examples will be discussed.
