Preparation and Characterisation of TiO2 Thick Films Fabricated by Anodic Oxidation
Anodic oxidation has been used to make well adhered and porous (≤1 μm pore diameter) thin films of anatase on titanium using electrolytic solutions with combinations of H2SO4, H3PO4, and H2O2. The crystallinity, film thickness, and pore size and number increase with time and voltage. The voltage is limited to ~180 V by electrolysis and/or breakdown and the film thickness is ≤3 μm.
