Violet tungsten oxide, also known as purple tungsten oxide (VTO), is a typical defect state tungsten oxide. It is extremely suitable for new functional glasses due to its moderate band gap and good electrochromic properties. The significant specific surface area and excellent chemical stability of VTO powder can make the comprehensive performance of the prepared electrochromic glass better, which is mainly reflected in environmental protection, energy saving, high efficiency and other aspects.
Compared with photochromic glass technology and thermochromic glass technology, electrochromic glass technology is easier to realize. It uses an external electric field to change the color of the material, so as to achieve active and dynamic control of light and solar radiation heat. Electrochromic glass has the ability to adjust light absorption and transmission under the action of electric field, which can effectively control external heat radiation and internal heat diffusion, and reduce the large amount of energy that must be consumed by buildings to maintain indoor temperature. It is an energy-saving building. Functional Materials.
Compared with ordinary glass, the reason why electrochromic glass has a better energy-saving effect is mainly because the product contains electrochromic materials. Electrochromism refers to the phenomenon that the optical properties of materials (reflectivity, transmittance, absorptivity, etc.) undergo stable and reversible color changes under the action of an external electric field, and the appearance is manifested as reversible changes in color and transparency.
Electrochromic materials can be divided into inorganic electrochromic materials and organic electrochromic materials. Compared with organic electrochromic materials, inorganic electrochromic materials are more environmentally friendly and healthy, and the current representative product is tungsten oxide. According to the different oxygen content, tungsten oxide can be divided into yellow tungsten oxide, blue tungsten oxide, purple tungsten oxide and tungsten dioxide. Among them, the physical and chemical properties of violet tungsten powder are more prominent.
