Summary of electrochromic glass trends:

1, all solid state, intelligent, large size

In terms of the development trend of electrochromic glass technology, all-solid electrochromic glass technology is the main direction of electrochromic technology research and development because of its excellent stability and weather resistance. WO3 and NiOx non-electrochromic materials are still the first choice for electrochromic materials with good chemical stability, simple preparation process, high bonding strength with substrate and easy realization of all-solid state. Improving the electrochromic properties of WO3 and NiOx by doping different substances is a research focus. Non-polymer solid electrolyte lithium salt has high conductivity and good chemical stability, and is the best choice for electrolytes required by electrochromic technology. High conductivity and good light transmittance are the main criteria for selecting transparent conductive layer. Fluorine doped tin oxide film and tin doped indium oxide film are the most commonly used transparent conductive layer materials at present. All-solid, intelligent, large size is the main direction of electrochromic glass technology development.

2, energy-saving, automatic intelligent

With the increasingly severe global energy crisis and environmental crisis, energy conservation and emission reduction are urgent. Energy consumption mainly comes from industrial energy consumption and building energy consumption. In order to pursue the beauty of modern high-rise buildings, a large number of glass Windows and curtain walls are adopted. Ordinary glass is difficult to control the transmission and reflection of light, and can not achieve the effect of heat insulation, which greatly increases the energy consumption of lighting and air conditioning. In the context of energy shortage and excessive greenhouse gas emissions, in order to reduce this part of the energy consumption enterprises use energy-saving glass, energy-saving glass insulation, shading effect is good, but the lighting may be affected, and can not be adjusted according to the environmental transmittance and reflectivity of light. The new generation of smart glass represented by electrochromic glass absorbs the advantages of energy-saving glass, and can also be controlled by the sensor automatically or artificially to continuously and dynamically adjust the color of the reflected light intensity, which has become the current development trend.

Market competition pattern: At present, the main competitors in the electrochromic glass market include SAGE Electrochromics in the United States, AGC in Japan, Shanghai SAN 'an in China, Merck in Germany and other companies. These enterprises have certain advantages in technology research and development, product innovation, and market expansion.

Market prospect: With the continuous development of technology and the continuous expansion of application fields, the electrochromic glass market has a very broad prospect. In the future, electrochromic glass will be applied in more fields, and the market size will continue to expand. In general, the electrochromic glass market is a market full of opportunities and challenges, and enterprises need to make continuous efforts in technology research and development, product innovation, market expansion, etc., in order to occupy a place in the market competition.

Field of application of color-changing glass

With the shortage of energy, the research and development of energy-saving materials has become an important issue of widespread concern. The all-solid smart window (SW) with electrochromic materials as the core can dynamically adjust the output or input of solar energy and the visible spectrum, and can also be used as the windshield and large-area display of vehicles such as automobiles. It has wide application prospect in construction, transportation and electronics industry. Electrochromic glass has been widely used in construction, aircraft, automobile and other fields.

Application prospect of color-changing glass

(1) information storage components: The use of photochromic compounds by different intensity and wavelength light can be repeatedly cycled color characteristics, can be made into computer memory storage components, to achieve information memory and elimination process. The density of the recorded information is unimaginably high, and the fatigue resistance is good, and the information can be written and erased quickly. This is a new development direction of new memory storage materials. 

(2) Decorative and protective packaging materials: photochromic compounds can be used as nail paint, lacquer carving crafts, T-shirts, wall paper and other decorations. In order to meet different needs, photochromic compounds can be added to general ink or paint used in adhesives, diluents and other additives mixed to make screen printing ink or paint; Photochromic compounds can also be made into packaging films, dimming glass Windows of buildings, screen glass of automobiles and aircraft, etc., to protect sunlight and ensure complete protection.

 (3) Self-developing holographic recording: This is a new type of self-developing + method photography technology made of the photosensitivity of photochromic materials. A thin layer of photochromic material (such as spiropyranan, capraxine, etc.) is coated on a support body such as a transparent film, which is not sensitive to visible light but only sensitive to ultraviolet light to form a colored image. This imaging method has high resolution, no operational error occurs, and the image can be recorded and erased anyway. 

(4) National defense uses: photochromic materials are particularly sensitive to strong light, so they can be used to make strong light radiation dosing. It measures ionizing radiation, detecting doses of ultraviolet, X-rays, y rays, etc. If it is applied to the outside of a spacecraft, it can quickly and accurately measure the dose of high radiation. Photochromic materials can also be made into multi-layer filters to control the intensity of radiation and prevent ultraviolet damage to the human eye and body. If the highly sensitive photochromic system indicator screen is used on weapons, it can record the whereabouts of aircraft and warships, forming a temporary trace that can fade
