Abstract

The invention relates to the field of electrochromism and particularly relates to an organic silicon modified acrylate based electrochromic device and application thereof in the field of rearview mirror preparation. The electrochromic device comprises an electrolyte layer, and the electrolyte layer is formed by organic silicon modified gel electrolyte available for ultraviolet curing and border adhesives used for packaging devices surrounding the gel electrolyte. The electrochromic device has advantages of cheapness, high conductivity, high response speed, solar radiation resistance, high permeability and the like, and a preparation process is simple. Electrochromic rearview mirrors manufactured by adoption of the electrochromic device are high in electrochromic speed, uniform in electrochromism and high in cycling stability and have a promising application prospect in the field of automobile rearview mirrors.

Description

technical field [0001] The invention belongs to the field of electrochromic, in particular to an electrochromic device and its application in the field of rearview mirror preparation. Background technique [0002] In the modern society with increasingly developed economy, cars have become very common in our lives. As an integral part of the car, the rearview mirror can reflect the situation behind, side and below the car, so that the driver can indirectly see these things clearly. Depending on the location, it acts as a "second eye" and expands the driver's field of vision. When driving at night, the driver will be dazzled by the strong light coming from the rear and have a short-term blurred vision, which will greatly threaten the safety of the driving person, and even endanger the safety of life in severe cases. The electrochromic rearview mirror absorbs most of the irradiated light, so that the reflectivity of the discolored rearview mirror is only about 10%, which can w...
