Nano Tungsten Oxide Applied for Window Heat Insulation Film

Nano tungsten oxide may be applied for producing window heat insulation film. And therefore, such films can be applied in car windows or building windows. The photochromic properties or electrochromic properties of tungsten oxide will be reflected in accordance with its application mechanism.nano tungsten oxide applied for window heat insulation film picture
When tungsten oxide is used in practical applications as an electrochromic device, it has a long color retention time, which shows a certain storage memory ding. This property requires an ion conductor layer in an electrochromic device must have a certain barrier effect on electrons in addition to having a higher ion transport rate, so as to reduce the occurrence of internal leakage and slow down the color change reaction proceeds spontaneously in the fading direction under uncontrolled condition. This property can be improved by the electrolyte material of the ion conductor layer. In fact, it is one of the main factors that restrict the research, development direction and application range of electrochromic materials.
