Influence of Electrolytic Mediums on Microstructure of Anodic Titania Film

Abstract:

Surface characteristics of anodic titania formed by electrochemical method and effects of electrolytic mediums on microstructures of anodic TiO2 layer were investigated. The titania film formed in sulfuric acid or mixture electrolyte with sulfuric and phosphoric acids shows porous cell structures. But the films formed in sulfuric acid represent smaller cell structures than those formed in the mixture electrolyte, and the change in microstructural parameters is associated with electrolytes. However, when titanium substrate was anodized in HF, surface morphologies and structures of anodic titania film greatly changed, forming self-organized TiO2 nanotubes.
