preparation example Construction

[0030] In addition, an embodiment of the present invention also provides a method for preparing an electrically controlled color-changing glass, for example, for preparing the aforementioned electrically controlled color-changing glass 900 . The method for preparing electrically controlled color-changing glass, for example, includes the steps of:

[0031] S11: A glass substrate is provided. Clean and dry the glass substrate.

[0032] S12: Plating a first conductive layer on the glass substrate. Specifically, the glass substrate is heated to a preset temperature, the range of the preset temperature is, for example, 280-300°C, and one or a combination of at least two of FTO, ITO, IGZO, AZO, GZO, and Ag is used as the target The material is deposited under a first preset vacuum sputtering pressure to obtain a first conductive layer. The first preset vacuum sputtering pressure, such as 1.0E -3 ~9.0E -3 mbar. Preferably, the first conductive layer may also be a pre-prepared c...

Abstract

An embodiment of the invention discloses electrochromic glass, which comprises a glass substrate, and a first conducting layer, a first composite photochromic layer, an ion conductor layer, a second composite photochromic layer, a second conducting layer and a medium protection layer which are sequentially positioned on the glass substrate, wherein materials of the first composite color-changing layer and the second composite color-changing layer comprise a first color-changing material and a second color-changing material respectively, the first color-changing material is selected from oxides of at least two combinations of W, Mo, Nb, Ti and Ta, and the second color-changing material is selected from oxides of at least two combinations of Ni, V, Co, Ir, Fe and Mn. According to the electrochromic glass, the electrochromic uniformity of large-area product devices can be improved.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to an electrically controlled color-changing glass. Background technique [0002] At present, in the process of industrialization of electronically controlled color-changing glass, there are still many defects in the color-changing uniformity of large-area product devices and the cycle life of color-changing cycles. The color-changing materials are mainly WO 3 Material. WO 3 The material is a well-known high-efficiency cathodic color change material, through chemical oxidation and reduction reactions, control WO 3 The change of the valence state of W in the medium can realize the absorption regulation effect on the spectrum. However, due to its large area of ​​uneven discoloration and short cycle life, after a certain number of cycles, the discoloration function near the electrode is severely attenuated or even does not change color, which greatly affects its application in enginee...
