Nano tungsten oxide, which may be applied for preparing ceramic microsphere, is an excellent electrochromic material with good stability, mainly showing in the following two features: 1. It has better structural stability during color reversible change process, which requires electrochromic materials to be less prone to irreversible structural damage during ion insertion and extraction, thus showing good reversibility of redox and color change, and long cycle life. 2. With high chemical stability, good weather resistance and corrosion resistance, it can…

Nano tungsten oxide may be used in heat insulating window glass, which is mainly to shield the ultraviolet (UV) and infrared rays, thereby reducing the temperature inside the car and improving the comfort of human body. Tungsten oxide can also be used on electrochromic devices with excellent electrochromic properties. And therefore, such electrochromic devices will have shorter color change response time, i.e., higher color conversion rate. This requires that the entire color change reaction have higher reaction rate under the…

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. 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…

Nano tungsten oxide may be applied in the field of thermal insulating glass with excellent thermal insulation properties and high visible light transmittance. Tungsten oxide also has electrochromic properties and therefore can be used on electrochromic devices. The electrochromic device is generally composed of five-layer structure, which can be divided into two transparent conductor layers (TC), a counter electrode layer (CE), an ion conductor layer (IC), and an electrochromic layer (EC) sandwiched therebetween. If tungsten oxide is used as an…

Nano tungsten oxide, which may be applied for producing heat insulation coating, is an n-type semiconductor material and a “d0” oxide. Such two features make tungsten oxide have many advantages at the same time. Although tungsten oxide is often present in various structures such as amorphous structure, monoclinic structure, and hexagonal structure, while its main structure is composed of tungsten-oxygen octahedron connected end to end. Depending on the crystal structures and surrounding environment, the octahedral unit will be distorted in…

Nano tungsten oxide may be used to produce thermal insulation coating with excellent photochromic properties. Tungsten oxide is also a type of electrochromic material. It is worth noting that the reversible transformation process of tungsten oxide and tungsten bronze is always accompanied by the transfer of internal electrons and the change of tungsten valence, which will induce a color change reaction and achieve controllable adjustment of transmitted light. This feature was first discovered in 1969 and has since been widely…

Nano tungsten oxide may be used for the preparation of near-infrared shielding material, which plays the role of “heat insulation, energy saving and anti-glare”, mainly reflecting its photochromic properties. As a new dingal material, tungsten oxide has many excellent characteristics such as easy synthesis, low energy consumption, wide viewing angle, long working life, good stability, high coloring efficiency, low production cost, and strong color contrast, etc. Such advantages make tungsten oxide become one of the research hotspots in the field…

Nano tungsten oxide may be used for the preparation of nano-ceramic dispersion solution. Tungsten oxide can also be used in smart windows, which mainly reflects its electrochromic properties. And such smart windows are mainly to meet different requirements of people for room temperature and daylighting in different seasons and different time periods as the heat insulation performance of tungsten oxide is excellent with high visible light transmittance. The heat insulating film of tungsten oxide has become a hot spot in…

Nano tungsten oxide may be applied for preparing thermal insulation film. This kind of heat insulation film is a type of excellent building energy-saving material, which can be applied in various architectural glasses. Due to environmental protection, energy conservation and rising energy prices, transparent heat insulation film of tungsten oxide has received more and more attention at home and abroad. Therefore, the problem of energy consumption control in building heating and cooling has also arisen. Among them, the energy loss…

Nano tungsten oxide has excellent thermal insulation properties so that it may be applied for manufacturing thermal insulation paper. Tungsten oxide may also be applied in architectural glass to reduce building energy consumption. According to relevant data, more than 86% of the existing 43 billion square meters of buildings in China still use ordinary single-layer glass, which has poor thermal insulation performance. Faced with the urgent demand for low energy consumption in buildings in the current market, various energy-saving glasses…
