Combination switchable glass composite window and preparation method thereof

Abstract

The invention relates to a combination switchable glass composite window and a preparation method thereof. The composite window and the preparation method thereof include a substrate, and a first outer ITO transparent conductive film layer, an electrochromic layer, an ion transport layer, an ion storage layer and a second outer ITO transparent conductive film layer which are sequentially arranged on the outer surface of the substrate, and further include an inner ITO transparent conductive film layer, a PDLC liquid crystal light-adjusting film and an ITO transparent conductive film which are sequentially arranged on the inner surface of the substrate, wherein ordinary glass, toughened glass, laminated glass, organic glass or a mixture thereof is selected and used for the substrate, tungsten oxide is selected and used for thin-film material of the electrochromic layer, a lithium ion thin film is selected and used for an ionic conductive layer, and nickel oxide thin film is selected and used for the ion storage layer. The composite window and the preparation method thereof have the advantages that a combination of the electrochromic layer and the PDLC liquid crystal light-adjusting film combines the advantages and disadvantages of both and further effects of intelligent light adjusting and light shielding can be achieved.

Description

technical field [0001] The invention belongs to the field of electrochromic devices and polymer dispersed liquid crystal dimming devices, in particular [0002] The invention relates to a combined dimming glass composite window and a preparation method thereof. Background technique [0003] With the depletion of earth's resources and the excessive impact of human beings on the environment, green, environmentally friendly, energy-saving and low-carbon materials have become a research hotspot. Color-changing materials are new functional materials developed under this situation. [0004] Electrochromic material is a promising functional material. It has broad application prospects in large-scale displays, optical switches, glare-free mirrors, electrochromic storage devices, architectural window glass, and smart windows. Devices made of chromogenic materials are called electrochromic devices. [0005] Polymer-dispersed liquid crystal (PDLC) is to mix low-molecular liquid cryst...

Problems solved by technology

Its shortcomings and limitations are manifested in the change of transparency - shading, but it does not really block the line of sight (no privacy); while the basic structure of polymer dispersed liquid crystal (PDLC) is a composite material in which liquid crystal droplets are evenly dispersed in a polymer matrix, and This material can show two states of transparency and scattering under the switching action of the electric field; its disadvantage and limitation are two states of transparency and scattering - blocking the line of sight (protecting privacy), but not really blocking light
