Description

technical field [0001] The invention relates to an electrochromic device and a preparation method thereof. Background technique [0002] Under the action of an external electric field, the chemical valence and composition of electrochromic materials undergo reversible changes, resulting in changes in their optical properties, mainly manifested as color changes in the visible band. There are many kinds of electrochromic materials, mainly divided into organic electrochromic materials such as conductive polymers, organic small molecule dyes, etc. and inorganic electrochromic materials such as transition metal oxides and metal coordination complexes. Electrochromism has a wide range of application potentials in smart windows, anti-glare rearview mirrors, aerospace thermal control, and aircraft portholes. [0003] Traditional all-solid-state electrochromic devices generally include a five-layer structure of bottom electrode layer, electrochromic layer, electrolyte layer or ion-c...
