WO3 film is used as an EC film that has a color-changing ding in a five-layer film of an electrochromic smart window. So, do you know how the electrochromic window works? Experts take cathode coloring electrochromic materials as an example to introduce the working process of electrochromic devices. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html The working process of the electrochromic device is: Under the action of the applied voltage, the electrons provided by the transparent conductive layer and the positive ions…

Yellow tungsten oxide, that is, tungsten trioxide, can be used to prepare an electrochromic thin film and then be used to assemble an electrochromic smart window, including an all-solid-state electrochromic window and a semi-solid electrochromic window. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Experts said that in the all-solid-state electrochromic window structure, five layers of film including a transparent conductive film TC1, an electrochromic film EC, an ion conductor film IC, an ion storage film IS and a transparent conductive film TC2,…

Tungsten oxide can be used to prepare an electrochromic film for use in assembling an electrochromic smart window, thereby applying to building to achieve the purpose of heat insulation. Since the color changing process must have an electron source and an ion source in accordance with the principle of electrochromism, at present, the electrochromic windows is usually composed of five layers of film (excluding the substrate), as shown in the following figure. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html The five-layer film…

WO3, more precisely, a tungsten trioxide film, is an important raw material for preparing an electrochromic smart window – one of the best electrochromic materials for preparing electrochromic devices. So, in general, what performance should the electrochromic window have? More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html From the practical requirements, electrochromic windows should generally have the following properties: the transmittance is 50-60% at bleaching state, and the transmittance is 10-20% at coloring state. Open circuit memory capacity is more than 24h. Response…

Tungsten oxide can be applied to prepare an electrochromic film, and then be used to produce a new type of smart window, in which the WO3 electrochromic film plays a decisive role in the performance of the entire electrochromic window. In this regard, experts said that considering the performance, price and preparation process and other factors, from the current research results, tungsten oxide film is one of the best electrochromic materials. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html What are the requirements…

Tungsten trioxide can be applied in the preparation of electrochromic smart window in the form of an electrochromic film. And the electrochromic window using WO3 film as an EC layer material is considered to be the most promising electrochromic device. However, at present, the research on smart windows is far less than the research on electrochromic materials. Although some samples of electrochromic windows have been developed, it is still necessary to make more in-depth research and improvement on its structure…

Amorphous WO3 film has a good electrochromic effect, so it is a well-known and the most widely studied electrochromic material, more specifically, an inorganic electrochromic material. So, why does an amorphous tungsten trioxide film have a good electrochromic effect? More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html The reason why the amorphous tungsten trioxide film has a good electrochromic effect is that its crystal lattice is a three-dimensional disordered network structure. In addition to the formation of a quadrilateral channel, there are also…

Tungsten oxide nanorods may be applied for producing nano transparent heat insulation coating. And the raw material tungsten oxide nano powder can be prepared by solvothermal method. For example, some experts have prepared tungsten oxide (WO3-x) by solvothermal method using n-propanol as an alcohol solvent, a reaction temperature of 200°C, a reaction time of 24h, and a molar solution concentration of 10mM. The morphology of the tungsten oxide nanopowder was found to be nanorods with a diameter of about several…

Morphology of tungsten oxide nanoparticles will affect the performance of the prepared energy saving glass coating. In this regard, some experts have studied the effect of reaction temperature on the morphology of the tungsten oxide nanopowder. Experts adopted solvothermal method to prepare tungsten oxide nano powder using n-propanol as the alcohol solvent. Wherein, the molar concentration of the solution was 15mM, the reaction time was 24h, and the reaction temperature was 180°C (a), 200°C (b), and 220°C (c), respectively, in…

Tungsten oxide nanoparticles for building glass energy saving coating can be prepared by solvothermal method. For example, experts adopted this method to prepare nano particle size tungsten oxide to study the effect of solution concentration on the morphology of nano tungsten oxide when isopropanol was used as the alcohol solvent. Wherein, the reaction temperature was 180°C and the reaction time was 12h. The figure below shows the SEM image of tungsten oxide nanopowder at different solution concentrations. More details, please…
