Problems solved by technology

[0005] First of all, this method uses titanium dioxide solution as the cracking solution. Since the titanium dioxide sol is hydrolyzed in the air, it turns into a polycrystalline film, and the volume of the polycrystalline film shrinks severely during the drying process, resulting in severe warping of the crack, which will increase the width of the crack. , and then increase the metal line width, which affects the light transmission performance of the glass
[0006] Secondly, this method uses titanium dioxide solution as the cracking liquid. When removing the cracked template, because the physical and chemical properties of titanium dioxide are stable, the cracked template made by it can only be removed by mechanical friction. Not only the removal process is complicated, but also Mechanical friction will also wear the substrate and metal electrodes, affecting the light transmission and electrical conductivity of the glass respectively

specific Embodiment 2

[0040] The electrochromic glass of the present embodiment, on the basis of the specific embodiment 1, further defines that the conductive layer 5 of the connected metal network adopts such as figure 2 Made by the method shown. The method is a lift-off process, comprising the following steps:

[0041] In step a, the surface of the glass plate is first drop-coated with cracked nail polish containing water-based acrylic resin, and then the masking liquid is evenly coated on the surface of the glass plate by a spin coating method to form a mask layer film;

[0042] Step b, in a closed chamber, the temperature of the chamber is controlled to be 20-25° C., the humidity is 50-80% RH, and the mask layer film is naturally dried to form a crack template;

[0043] Step c, using magnetron sputtering or electron beam evaporation to deposit a conductive silver layer on the surface of the cracked template;

[0044] In step d, the cracked nail polish cleaning agent or chloroform solution i...

specific Embodiment 3

[0046] The electrochromic glass of this embodiment, on the basis of the specific embodiment 2, further defines the lift-off process,

[0047] The cracked nail polish described in step a is diluted with a diluent, and the dilution ratio k is defined as the volume ratio of the diluent to the cracked nail polish, and 1≤k≤7.

[0048] Under the above ratio conditions, it is found that the relationship between the average crack width w of the crack template and the film thickness h of the mask layer is:

[0049] w=0.342e 0.266h

[0050] In the formula, w is the average crack width of the crack template, in μm; h is the film thickness of the mask layer, in μm.

[0051] The relationship between the average crack spacing d of the crack template and the film thickness h of the mask layer is:

[0052] d=15.8e 0.169h

[0053] In the formula, d is the average crack spacing of the crack template, in μm; h is the film thickness of the mask layer, in μm.

[0054] These two formulas show...

Abstract

The invention relates to electrochromic glass. The electrochromic glass comprises an upper glass plate (1), a lower glass plate (2) and a bi-stable liquid crystal (4) arranged between the upper glass plate (1) and the lower glass plate (2) and sealed with filling rubber (3); the lower surface of the upper glass plate (1) and the upper surface of the lower glass plate (2) are provided with communicated metal network electricity conductive layers (5); each communicated metal network electricity conductive layer (5) comprises an electrode and a lead which are communicated with a metal network. As the electrodes of the electrochromic glass have good light transmittance performance and electricity conductive performance, the electrochromic performance of the glass is superior.

Description

technical field [0001] The invention relates to an electrochromic glass. Background technique [0002] Electrochromic glass is a glass with adjustable light absorption and transmission under the action of an electric field. It can selectively absorb or reflect external heat radiation and internal heat diffusion by changing the electric field. It has a wide range of applications in automotive, construction and other fields. In the field of automobiles, electrochromic glass can improve the natural light level and play a role of anti-peeping; in the field of construction, electrochromic glass can reduce the large amount of energy that must be consumed in office buildings and residential buildings to keep cool in summer and keep warm in winter . It can be seen that electrochromic glass has a wide range of applications. [0003] The invention patent "Electrochromic Glass" with the application number of 201210322733.8 discloses an electrochromic glass structure. This electrochr...
