Electrochromic material and preparation method thereof

Abstract

The invention relates to the technical field of electrochromic material preparation, and discloses an electrochromic material and a preparation method thereof. The electrochromic material is of a multi-layer hollow sphere structure, the outer diameter of the electrochromic material is 50-180 microns, the outer surface layer of the electrochromic material is a high-molecular polymerization product electrochromic material, iron is doped in the high-molecular polymerization product electrochromic material, the inner layer is made of a high-molecular polymerization product non-electrochromic material, and the thickness of the inner layer is 7-15 microns. A layer of inorganic metal film is plated on the surface of the high-molecular polymerization product electrochromic material, so that the physical and chemical properties of the high-molecular polymerization product electrochromic material are improved on the premise of not changing the electrochromic properties of the high-molecular polymerization product electrochromic material, the service life of the high-molecular polymerization product electrochromic material is prolonged, and the market competitiveness of the electrochromic material is improved.

Description

technical field

[0001] The invention relates to the technical field of electrochromic material preparation, in particular to an electrochromic material and a preparation method thereof. Background technique

[0002] Electrochromic materials refer to the phenomenon that the optical properties of materials undergo stable and reversible color changes under the action of an external electric field, and appear as reversible changes in color and transparency in appearance. Materials with electrochromic properties are called electrochromic materials. Electrochromic materials can be divided into inorganic electrochromic materials and organic electrochromic materials.

[0003] Both inorganic electrochromic materials and organic electrochromic materials have disadvantages. Although inorganic electrochromic materials have excellent physical and chemical properties, they are expensive, while organic electrochromic materials are cheap, but The physical and chemical properties are not s...
