Tungsten Oxide Grape Film Performance Advantages

The morphology and structure of the surface of the tungsten oxide film will largely affect the properties and applications of the tungsten oxide material. The difference of the microstructure will make the tungsten oxide film show different characteristics to the outside, and then, in various applications of the tungsten oxide film. The field gets different application and development. Tungsten oxide grape film belongs to the tungsten oxide film, which is a new surface topography.

The grape-like structure makes the tungsten oxide film has a larger specific surface area, a special grain size and other microstructural properties, which is conducive to the reaction of ion injection and extraction. At the same time, the chemical activity of the tungsten oxide film is also improved, the reaction between the proton and the metal oxide in the tungsten oxide film is strengthened, and the proton-electron conversion rate is improved.

The tungsten oxide grape-like thin film is usually prepared by electrolytic deposition using the property that the tungstophosphoric acid is agglomerated into a grape-like structure in the solution. When the tungsten oxide film particle size changes will bring quantum size effect, which has a great impact on the tungsten oxide film discoloration. The grape-like structure can increase the mobility of carriers in the tungsten oxide film, and thus the tungsten oxide grape-like film can exhibit excellent electrochromic properties.
