Titania nanotube arrays prepared in DMF/HF electrolytes

Fabrication of titania nanotube arrays by anodization of titanium foil in a fluorinated dimethylformamide (DMF) was investigated. The surface morphology of anodized samples were explored using scanning electron microscopy (SEM). The prepared anodic film has a highly ordered nanotube-array surface architecture. Compared with water-based electrolytes, much longer and smoother nanotubes can be grown in DMF electrolytes. Influence of applied potential on the topologies of the anodized titanium was also studied. Increasing the anodization potential results in longer nanotubes with greater diameter and wall thickness.
