pH Condition Influence Nanotube Structure of TiO2 by Anodizing Titanium Substrate / Nur Aimi Jani… [et al.]

The influence of pH of the electrolyte used during anodization of Titanium substrate has been investigated in order to determine the optimum pH condition to form self-organized Titanium dioxide (TiO2) nanotubes (NTs) structure. The TiO2 NTs was formed by anodizing Titanium substrate in an electrolyt...
