Embodiment 1

[0056] This embodiment provides a method for preparing a suspended particle-type smart window, which includes the following steps:

[0057] (1) setting a dielectric layer on the transparent substrate;

[0058] (2) curing the dielectric layer and performing a hydrophilic treatment;

[0059] (3) Make a crack template on the dielectric layer:

[0060] (4) Form a crack network transparent conductive electrode on the transparent substrate;

[0061] (5) preparation of modified nano titanium dioxide sol;

[0062] (6) The modified nano-titanium dioxide sol is injected between two cracked network transparent conductive electrodes and encapsulated to obtain a suspended particle smart window.

[0063] It includes four main steps: one is the preparation of dielectric materials and cracking fluid, and the other is the modification of nano-TiO 2 The preparation of the sol changes from water-soluble to oil-soluble. The third is to prepare the dielectric layer and the deposition of the cr...

Embodiment 2

[0086] What this embodiment provides is the intelligent window of suspension particle formula, and what differ from embodiment 1 is that nail polish (model is CA600, commercially available product) is mainly used as cracking liquid and CYTOP as dielectric layer and KH-570 as TiO 2 A modifying agent for nanoparticles, comprising the steps of:

[0087] (1) Preparation of dielectric materials, cracking fluid and

[0088] The method of preparing the cracking fluid is described in detail here.

[0089] Add 10mL of CA600 into the beaker, put it in an ultrasonic cleaner and shake it for 20min, put it in a centrifuge and centrifuge at 5500r / min for 5min, take out the solution and remove the lower sediment, the supernatant is the solution;

[0090] The method for preparing the dielectric layer solution is described in detail here.

[0091] Add 1.0mL of CYTOP diluent to beaker B, then add 1.0mL of 9%wt CYTOP solution, put it into an ultrasonic cleaner and vibrate for 20min, and prepa...

Embodiment 3

[0104] The suspended particle-based intelligent window based on the cracked grid provided in this embodiment is different from Embodiment 1 in that it mainly uses egg white cracking liquid, PAA dielectric layer and DTMS (dodecyltrimethoxy silane) as TiO 2 The modification of nanoparticles comprises the following steps:

[0105] (1) Preparation of dielectric materials, cracking fluid and

Abstract

The invention discloses a method for preparing a suspended particle type smart window, which comprises the following steps: (1) setting a dielectric layer on a transparent substrate; (2) curing the dielectric layer and performing hydrophilic treatment; (3) Making a crack template on the dielectric layer: (4) Form a crack network transparent conductive electrode on a transparent substrate; (5) Prepare a modified nano-titanium dioxide sol; (6) inject the modified nano-titanium dioxide sol into two cracks The network transparent conductive electrodes are packaged between them to obtain a suspended particle smart window. The method has the advantages of simple process, high efficiency, low cost, convenient mass production and easy realization of industrialization. The object of the present invention is also to provide a suspended particle smart window made by the above method, which has low drive voltage, low power, fast response, precise control, high light transmittance, and good chemical and thermal stability.

Description

technical field [0001] The invention belongs to the technical field of smart windows, and in particular relates to a preparation method of a suspended particle type smart window and the smart window. Background technique [0002] Smart windows (Smart windows) is an optical device composed of a substrate (glass or other transparent materials, etc.) Under the excitation of temperature), a coloring or fading reaction occurs in certain sections of the solar spectrum, causing the optical properties of the light-adjusting material to change, so that the spectrum selectively absorbs or reflects solar radiation, so as to shield ultraviolet rays, adjust the intensity of sunlight entering the room and the indoor and outdoor Heat exchange, reduce cooling and heating energy consumption, and reduce carbon emissions. When voltage, light or heat is applied, its light transmission properties change, generally from translucent to transparent, from blocking some (or all) of the wavelengths o...
