Formation and Properties of Anodic TiO2 Nanotubes — •Patrik Schmuki, Julia Kunze, Hiroaki Tsuchiya, and Jan Macak — Uni Erlangen, Dept Mat. Sci, WW4

We present the electrochemical fabrication of self-organized high aspect ratio titanium oxide nanotubes achieved by an optimized and controlled anodization of Ti in fluoride containing solutions. In general, the morphology and the structure of porous layers are affected strongly by the electrochemical parameters used. Under optimized conditions self-organized highly ordered nanotubes with a length of several micrometers are formed consisting of arrays with single tube diameter of approx. 100 nm and a tube interval of 150 nm. Titanium oxides is a highly functional material that has numerous interesting properties, for example, in solar energy conversion, catalysis of decomposition of organic compounds (self-cleaning), wettability and biocompatibility. Therefore the tubes provide a novel functional and nanoscopic TiO2 form for numerous applications.
