Abstract

The invention discloses an electrochromic device based on a multifunctional hydrogel electrolyte. The electrochromic device structurally comprises a layer of ITO electrode, an electrochromic layer and a layer of multifunctional hydrogel electrolyte, wherein the multifunctional hydrogel electrolyte replaces an electrode, an ion storage layer and an ion conducting layer of a traditional electrochromic device, electrons are transmitted to an electrochromic material on the surface of the hydrogel electrolyte through ITO when voltage is applied, and oxidation reduction occurs. The invention further provides a preparation method of the electrochromic device based on the multifunctional hydrogel electrolyte. According to the invention, the device is simple in structure, few in preparation steps, environment-friendly, good in repeatability and suitable for industrial production, and water is used as a solvent to reduce harm to human bodies.

Description

technical field [0001] The invention belongs to the technical field of electrochromic devices, in particular to an electrochromic device based on a multifunctional hydrogel electrolyte and a preparation method. Background technique [0002] Electrochromism (Eletrochromism) means that under the action of an applied voltage, a material can undergo a reversible oxidation-reduction reaction, thereby causing a stable and reversible change in the optical properties of the material in the visible light wavelength range, and the appearance shows a reversible change in color. The phenomenon. An electrochromic device with a display function is formed by assembling materials with electrochromic properties and corresponding ion-conducting layers, ion storage layers, and electrodes. In recent years, it has received extensive attention from many countries. Its application fields mainly include smart windows, electrochromic displays, smart dimming car rearview mirrors, military camouflage...
