preparation example 1

[0062] S1, blending, specifically,

[0063] Graphene oxide was dissolved in deionized water for ultrasonic dispersion, and 1.2 g of graphene oxide was added per 1 L of deionized water. The ultrasonic power is 300W, and the ultrasonic time is 30min. After the ultrasonication is completed, centrifuge at a speed of 7000rmp. After centrifugation, the supernatant is taken, and nitrogen gas is injected for 30min to remove the oxygen in the solution, and the graphene oxide solution is obtained for use.

[0064] Dissolve ferrous chloride tetrahydrate and ferric chloride hexahydrate in deionized water, add 0.15mol of ferrous chloride tetrahydrate and 0.2mol of ferric chloride hexahydrate for every 1L of deionized water, and stir to make the solid completely Dissolve, and then blow nitrogen into the solution for 30 minutes to remove the oxygen in the solution to obtain the iron ion solution.

[0065] Under the protection of nitrogen atmosphere, put the iron ion solution into the graphe...

preparation example 2

[0069] The difference between Preparation Example 2 and Preparation Example 1 is that the specific process of step S2 is different, and specifically includes the following steps:

[0070] S21. Primary deposition. Slowly add ammonia water dropwise to the mixed liquid obtained in step S1 until the pH of the system is 9. Incubate and deposit at a temperature of 70° C. for 1 hour, keep stirring at a stirring speed of 200 rpm to obtain a primary deposition liquid.

[0071] S22. Secondary deposition. Continue to add ammonia water dropwise to the primary deposition solution obtained in step S21 until the pH of the system is 10.5, and keep stirring for 1 hour to obtain the deposition solution.

preparation example 3

[0073] The difference between Preparation Example 3 and Preparation Example 2 is that in step S21, aqueous ammonia is added dropwise until the pH of the system is 9.5; in step S22, aqueous ammonia is added dropwise until the pH of the system is 11.

Abstract

The application relates to an intelligent atomized glass with low driving voltage and its preparation process. The intelligent atomized glass with low driving voltage includes a first transparent layer, an atomized layer, and a second transparent layer arranged in sequence, and the atomized layer includes at least the following raw materials in parts by mass: 30-50 parts of photocurable polymer; 50 parts of liquid crystal ‑70 parts; 0.1‑0.3 parts of magnetic graphene; 0.1‑0.2 parts of surfactant; 2‑5 parts of photoinitiator. The preparation method is as follows: step 1, dispersing the magnetic graphene to obtain a dispersion liquid; step 2, preparing a film layer to obtain a film liquid; step 3, assembling, coating the film liquid on the first transparent layer, and applying the second transparent layer The layer is covered on the first transparent layer to obtain a semi-finished glass; step 4, curing, and the dimming glass is obtained after being cured by ultraviolet light. The dimming glass of the present application has the effect of lower working voltage.

Description

technical field [0001] The present application relates to the field of dimming glass, in particular to an intelligent atomized glass with low driving voltage and its preparation process. Background technique [0002] Color-changing glass, also called dimming glass or adjustable transmittance glass, refers to glass that can change color under certain conditions such as light, current, external pressure, temperature, magnetic field, etc., and the color of the glass changes with the change of external conditions Changes, when the external conditions disappear, the glass will reversibly and automatically return to the original glass. [0003] At present, conventional switchable glass solutions on the market include PDLC (polymer dispersed liquid crystal), EC (electrochromic), etc., and the technical indicators of these switchable glasses have their own advantages and disadvantages. PDLC is a kind of structure in which liquid crystal droplets are uniformly dispersed in a cross-l...
