Abstract

The invention discloses an ion-conductive polymer electrolyte membrane, a preparation method thereof and electrochromic glass, belonging to the field of building materials. According to the preparation method, a membrane can be independently formed from a polymer electrolyte membrane by virtue of casting formation and can be compounded with an electrochromic layer formed on a first conductive glass substrate and an ion storage layer formed on a second conductive glass substrate, so as to assemble the electrochromic glass.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an ion-conducting polymer electrolyte film, a preparation method thereof and electrochromic glass. Background technique [0002] It is estimated that the energy consumption of buildings in my country will reach about 40% of the total energy consumption of the whole society in 2030, and 30-50% of the energy consumption of buildings will be lost by windows. The energy-saving and comfortable green intelligent building material, electrochromic glass, has become the first choice for reducing building energy consumption. The currently widely accepted electrochromic glass is "glass︳transparent conductive layer (TC)︳electrochromic layer (EC)︳ionic conductor layer (IC)︳ion storage layer (IS)︳transparent conductive layer (TC)︳glass "Sandwich structure. The main functional part where electrochromism occurs is the electrochromic layer. The role of the ion conductor layer is to...
