Wireless Anodization of Ti in Closed Bipolar Cells

In this work, the anodization of Ti foils in closed bipolar cells is shown for first time. Depending on applied potential, i. e. direct or alternating TiO2 nanotube (TNT) layers can either be prepared one side both sides a foil. It that due to use cells, potentials with different amplitudes within individual two half-cells. Additionally, electrolytes used substrate. Thus, TNT obtained under potential foil have completely dimensions, diameter and layer thickness. Furthermore, by employing potentials, black synthesized foil, while being reduced during last step at negative potentials.
