Abstract

Porous anodic aluminium and titanium oxides are investigated. An equifield strength model is proposed to explain the formation of the pores and their self-adjustment of ordering. High-resolution transmission electron microscopy analysis revealed a double-layer structure in the anodic titanium oxide nanotubes. It is also shown that the porosity of the porous anodic oxide film is mainly governed by the relative dissociation rate of water.
