Problems solved by technology

At present, the application of hydrogel in electrochromic devices mainly focuses on gel electrolytes. Electrochromic materials are usually attached to the electrodes in the form of thin films or free in the electrolyte in the form of small molecules. The thin films are easy to fall off and the response speed is slow. The problem

Abstract

A flexible electrochromic device and a preparation method thereof of the present invention belong to the field of electrochromic technology. The flexible electrochromic device consists of two layers of flexible transparent conductive electrodes and an electrochromic electrode attached between the two layers of conductive electrodes. The gel is formed, and its preparation method includes the preparation of electrochromic gel and the preparation of flexible electrochromic devices. The invention combines the electrochromic layer and the electrolyte layer to prepare the electrochromic gel, which not only effectively simplifies the structure of the electrochromic device, reduces the manufacturing cost, but also facilitates ion transmission and improves the electrochromic performance . In addition, devices based on electrochromic gel materials are flexible and stretchable.

Description

A flexible electrochromic device and preparation method thereof technical field The invention belongs to electrochromic technical field, relate to a kind of solid electrochromic device and preparation method thereof and application use. Background technique Electrochromic refers to that under the action of external electric fields such as positive and negative or high and low voltages, the color or transparency occurs on the macroscopic level. A reversible change in lightness, that is, a change in optical properties such as transmittance or reflectance of a material. Electrochromic devices are based on It is realized because of the above characteristics of electrochromic materials, and is widely used in smart windows, glare-free mirrors, displays and military and other fields. Traditional electrochromic devices are mostly rigid electronic devices made of glass substrates. In recent years, with the wearable With the rapid development of wearable and portable elec...
