preparation example Construction

[0027] In addition, the embodiment of the present invention also provides a method for preparing an electronically controlled tinting glass, for example, for preparing the aforementioned electronically controlled tinting glass 700 . The preparation method of electronically controlled tinted glass, for example, comprises the steps of:

[0028] S11: providing a substrate. Clean and dry the substrate.

[0029] S12: forming a first transparent conductive layer on the substrate. Specifically, the 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 preset vacuum sputtering pressure to obtain the first transparent conductive layer. The preset vacuum sputtering pressure is, for example, 1.0E -3 ~9.0E -3 mbar. Preferably, the first transparent conductive layer may also be a pre-prepared conduc...

specific Embodiment

[0043] An electronically controlled toning glass, the film layer structure from the substrate to the outside is: substrate / ITO(150nm) / WMoOx(200nm) / NiVOx(80nm) / Li(40nm) / ITO(150nm) / WMoOx(200nm) / Li(40nm) / NiVOx(80nm) / ITO(120nm) / Si 3 N 4 (20nm).

[0044] The process of preparing this electronically controlled tinting glass is as follows:

[0045] (1) The substrate is cleaned and dried, laser scribed, then cleaned and dried, and placed in a vacuum sputtering area;

[0046] (2) Deposit the ITO layer on the substrate by means of magnetron sputtering, the target used is an ITO rotating target, the power supply is DC or an intermediate frequency power supply with a frequency of 2000-40000Hz, the power is 1-30KW, and the process gas is argon , deposited at a temperature of 290°C;

[0047] (3) The WMoOx layer is deposited on the ITO layer by magnetron sputtering. The target used is a metal WMo planar target, the power supply is a DC power supply, and the power is 1-30KW. The process ...

Abstract

The embodiment of the invention discloses electric control color matching glass. The electronic control color matching glass comprises a substrate, and a first transparent conductive layer, a first main color matching layer, a first ion conductor layer, a first auxiliary color matching layer, a second transparent conductive layer, a second auxiliary color matching layer, a second ion conductor layer, a second main color matching layer, a third transparent conductive layer and a protective layer which are sequentially formed on the same side of the substrate. The color-changing uniformity of the electronic control color-matching glass in a large-area product device can be improved.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to an electronically controlled tinting glass. Background technique [0002] At present, in the industrialization process of electronically controlled color-changing glass, there are still many defects in the color-changing uniformity and color-changing cycle life of large-area product devices in electronically controlled color-changing products. The inorganic 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 the large area of ​​uneven discoloration and short cycle life of the current electronically controlled color adjustment products, after a certain number of cycles, the discoloration function near the elec...
