Tungsten Trioxide Electrodeposition Method

Tungsten trioxide electrodeposition method refers to the tungsten oxide from its aqueous solution of compounds, non-aqueous solution or molten salt electrochemical deposition process. Metal electrolytic smelting, electrolytic refining, electroplating, electroforming process foundation.

These processes are carried out under certain electrolyte and operating conditions. The ease of metal electrodeposition and the morphology of the deposit are related to the properties of the deposited metal, and also depend on the electrolyte composition, pH, temperature, current density and other factors.

The tungsten trioxide prepared by the electrodeposition method solves the limitation of the hydrothermal method on the tungsten trioxide substrate. The three-dimensional vertical structure hydrated tungsten trioxide nano-sheets can be formed by depositing hydrated tungsten trioxide nano-sheets prepared by a simple green solution method on a conductive substrate. This tungsten trioxide has a large light modulation range, a higher coloring efficiency, a shorter coloring time and response time, and a higher coloring efficiency. Through this work not only get a high performance, low cost electrochromic devices. It also provides a new method for constructing porous structure films. And this kind of vertical structure preparation method can be applied to the stretchable device in the future to prevent the film from cracking during the stretching process.

Tungsten trioxide electrodeposition method to get rid of the hydrothermal growth method of tungsten oxide dependence on the seed layer. Eliminating the seed-assisted hydrothermal preparation of thin film seed layer blocking the electrons. Improve the electronic transmission speed and electronic transmission efficiency. Therefore, compared with the seed-assisted film prepared, tungsten trioxide electrodeposition method has more excellent conditions.
