Embodiment 1

[0019] Embodiment one, such as figure 1 , 2 As shown, a color-changing glass in this embodiment includes double-layer glass 1, and double-layer glass 1 can adopt float glass or lattice glass or plexiglass or toughened glass, and a closed cavity is formed between double-layer glass 1, The airtight cavity is filled with electrochromic material 2, which is doped with conductive particles 3. The conductive particles 3 are non-spherical particles, and the two ends of the conductive particles 3 in the length direction are free ends respectively. A group of conductive terminals is provided; when a group of conductive terminals is not powered on, the atoms in the confined space are arranged vertically, and the two free ends face the upper and lower end faces of the double-layer glass 1; Due to the potential difference, the conductive particles 3 originally arranged vertically are arranged horizontally, and the two free ends extend along the length direction of the double-layer glass ...

Embodiment 2

[0023] Embodiment two, such as image 3 As shown, different from Embodiment 1, two cavities are formed in the double-layer glass 1, and the inner surface of each cavity is provided with a transparent electrode film 4, and the electrochromism is arranged in the transparent electrode film 4; The circular polarization of the colored light that can be generated by the electrochromic material 2 in the cavity is opposite, and the difference between the main luminous wavelengths is less than 8 nanometers.

Embodiment 3

[0024] Embodiment three, such as Figure 4 As shown, the difference from the second embodiment is that an insulating layer 5 is provided between the electrochromic material 2 and the transparent electrode film 4, and the insulating layer 5 is made of polyacrylic acid film. In addition, a glued layer is arranged between the double-layer glass 1, and a pouring port (not shown in the figure) is arranged on the glued layer.

Abstract

The invention discloses photochromic glass. The photochromic glass comprises two layers of glass, a sealing cavity is formed between the two layers of glass and filled with an electrochromic material,and conductive particles are mixed with the electrochromic material and are non-spherical particles; the two ends of each conductive particle in the length direction are free ends respectively, and the two layers of glass is provided with a set of conductive terminals; when a set of conductive terminals are powered off, atoms in a sealed space are vertically arrayed, and the two free ends face the upper and lower end faces of two layers of glass; when a set of conductive terminals are powered on, due to the potential difference, the powered-on conductive particles which are originally and vertically arrayed are changed to be horizontally arrayed, the two free ends extend in the length direction of the two layers of glass, and stable and reversible color change of the electrochromic material occurs under the effect of an external electric field. According to the photochromic glass, the transmissivity of the photochromic glass which is powered off and the shielding effect of the photochromic glass which is powered on are improved.

Description

technical field [0001] The invention relates to a color-changing glass. Background technique [0002] Electrochromism refers to the phenomenon that the optical properties of materials (reflectivity, transmittance, absorptivity, etc.) undergo a stable and reversible color change under the action of an external electric field, which is manifested as a reversible change in color and transparency in appearance. Materials with electrochromic properties are called electrochromic materials. Electrochromic materials are a new type of functional materials, which are widely used in information, electronics, energy, construction and national defense. Devices made of electrochromic materials are called electrochromic devices. An electrochromic device (ECD) is a device that uses the electrochromic effect of a substance, is based on an electrochromic layer, and is supplemented by other related layers and structures. It has unique advantages such as wide viewing angle, low driving voltag...
