Abstract

The invention relates to an electrochromic composite material and an electrochromic device and a preparation method thereof. The electrochromic composite material comprises a conductive layer and a thermochromic layer. The thermochromic layer is laminated on the conductive layer and comprises a first flexible polymer base body and an organic phase change material, the organic phase change material is opaque at normal temperature, and the first flexible polymer base body is transparent at normal temperature. The conductive layer comprises a second flexible polymer base body and a conductive material evenly deposited on the base body. The conductive material is a transparent conductive material. The electrochromic device comprises the electrochromic composite material and at least two electrodes. The electrodes are arranged at intervals and electrically connected with the conductive layer. The electrochromic device based on the electrochromic composite material has the advantages of being simple in preparation process, low in cost, good in flexibility and bendable, and accordingly can be applied to the fields of smart windows, energy saving buildings and military camouflage and the like.

Description

technical field [0001] The invention relates to the technical field of functional materials and devices, in particular to an electrochromic composite material, an electrochromic device and a preparation method thereof. Background technique [0002] Electrochromism refers to the phenomenon that the color or light transmittance of a specific material changes reversibly under the action of a certain electric field or voltage, and the appearance shows a reversible change in color and transparency. Electrochromic material is a new type of functional material with good physical and chemical properties. Its optical performance is continuously adjustable in a wide range, has a memory function, can maintain a colored state or a transparent state after being opened, has no visual restrictions, and has a wide working range. [0003] The preparation method of traditional electrochromic devices is mainly to deposit or polymerize electrochromic thin films on conductive glass, so there ar...
