High-efficiency uniformly colored hook face electrochromic transparent element and preparation method thereof

Abstract

The invention relates to a high-efficiency uniformly colored hook face electrochromic transparent element and a preparation method thereof. The preparation method includes the following steps: a firstsubstrate and a second substrate of the high-efficiency uniformly colored hook face electrochromic transparent element are pretreated and cleanedup through deionized water; surfaces of the first substrate and the second substrate are correspondingly plated with various transparent film layers under a vacuum state when the first substrate and the second substrate enter a vacuum chamber; under thecondition that a circuit works normally, a plurality of conductive channels are designed correspondinglyin the various transparent film layers within the range of a visible area of the high-efficiencyuniformly colored hook face electrochromic transparent element; and transparent conductive strips are correspondingly extended inside the conductive channels. According to the high-efficiency uniformly colored hook face electrochromic transparent element and the preparation method thereof, uniformity of the thickness of the film layers is achieved by setting sputtering process parameters reasonably and controlling the gradient change of the running speed from one side edge to the other side edge when target materials sputter the first substrate and the second substrate, so that the formed high-efficiency uniformly colored hook face electrochromic transparent element changes color evenly.

Description

technical field [0001] The invention relates to a curved surface electrochromic transparent device, in particular to a curved surface electrochromic transparent device with high efficiency and uniform color change and a preparation method thereof. Background technique [0002] With the rapid development of science and technology and the improvement of living standards, people have higher and higher requirements for the appearance and use experience of industrial products. For electrochromic devices with intelligent and fast color changing functions, changeable and soft curved surfaces that are more in line with public vision, and curved surface shapes such as aerodynamic streamline shapes that meet the requirements of products in the fields of locomotives, ships, aerospace and other fields, electrochromic devices are more and more popular in engineering. Attention of developers and users. [0003] The core component of curved surface electrochromic device is the combination...

AI Technical Summary

Problems solved by technology

[0005] Since the surface of the transparent substrate to be acted on is a special-shaped curved surface (including single and hyperboloid surfaces), the sputtering angle and sputtering distance will vary greatly during the sputtering process of the target material, resulting in uneven film thickness of the prepared film. And then affect the color uniformity of the electrochromic device

[0006] In addition, some large-area electrochromic devices also have the problems of excessive potential drop and insufficient driving force for color change, resulting in poor uniformity of color change and slow response speed.
