Description

Technical Field

[0001] The present invention belongs to the technical field of glass preparation, and particularly relates to a preparation method of interlayer color-changing glass. Background Art

[0002] Color-changing glass can be applied to architectural glass, automotive glass, aviation glass, decorative glass, etc. Currently, the most typical film structure of color-changing glass is a sandwich-type five-layer structure: glass / TC (transparent conductive layer) / EC (electrochromic layer) / IC (ion conductor layer) / CE (ion storage layer) / TC (transparent conductive layer) / glass. The most crucial part for realizing color change is the IC (ion conductor layer), also known as the lithium-ion electrolyte layer. This electrolyte layer must have good ionic conductivity and no electronic conductivity. That is, under the drive of voltage, lithium ions can be repeatedly injected and extracted in the color-changing layer. According to the usage characteristics of architectural glass, this injection and extraction need to reach at least tens of thousands of times without failure. Lithium is a tool for carrying charges, and a high ion transference number can make the dimming and color-changing effect of the product more excellent. Therefore, it is necessary to ensure a high ion mobility and no large attenuation during the process of injecting and extracting lithium ions. When the electrolyte is in direct contact with the color-changing layer or the electrode, side reactions are not desired, which requires the electrolyte to have a certain chemical stability. As architectural glass, the electrolyte must also have excellent thermal stability.
