Detailed Description
Example 1
(1) Preparation of tin antimony oxide Dispersion
Firstly weighing 1g of tin particles and 0.2g of antimony trioxide powder, placing the tin particles and the antimony trioxide powder into a 100mL three-neck flask, then adding 8mL of sulfuric acid into the three-neck flask, heating and stirring the mixture for 48 hours at 95 ℃, after the heating and stirring are completed, placing the three-neck flask into an ice water bath, slowly dropwise adding 32mL of hydrogen peroxide into the three-neck flask, after 20 minutes, adding 24mL of ultrapure water into the ice water bath under stirring, finally transferring the mixed solution into a hydrothermal reaction kettle, reacting the mixed solution for 10 hours at 160 ℃, centrifugally separating the mixed solution after the reaction is completed, drying the obtained solid, and grinding the solid into powder to obtain the antimony oxide powder; putting 25mg of tin antimony oxide powder into 450 mu L of ultrapure water, then adding 50 mu L of triethylamine into the ultrapure water, and dispersing the tin antimony oxide into the ultrapure water after violent shaking to obtain a tin antimony oxide dispersion liquid;
(2) weighing 5g of polyvinyl alcohol, dissolving the polyvinyl alcohol in 95mL of ultrapure water, heating and stirring the polyvinyl alcohol for 2h at the temperature of 80 ℃, completely mixing to obtain a polyvinyl alcohol solution, and placing the polyvinyl alcohol solution at normal temperature for later use.
(3) Synthetic tin antimony oxide high molecular film
Adding 500 mu L of polyvinyl alcohol solution into the tin antimony oxide dispersion liquid, oscillating for 30min, uniformly coating the mixed solution on a target 5 x 5cm glass sheet, and drying at room temperature for 24h to obtain a tin antimony oxide polymer film deposited on the glass sheet, wherein the obtained glass is the tin antimony oxide coated Low-E glass. It can be seen from fig. 1(a) that the thin film has an obvious lamellar structure, and it can be seen from fig. 1(b) that the circle marked part on the tin antimony oxide nano polymer film has the uniformly dispersed tin antimony oxide particles deposited, which proves that the tin antimony oxide nanoparticles are uniformly dispersed on the nano polymer film, and it can be seen from fig. 2(a) and fig. 2(b) that the regular lattice stripes of the tin antimony oxide nanoparticles can be seen in the high power transmission diagram, and they are uniformly distributed in the whole system in a net shape, which shows that the tin antimony oxide is highly dispersed in the polymer film, and it can be seen from fig. 3 that the characteristic peaks of polyvinyl alcohol and tin antimony oxide can be observed on the tin antimony oxide nano polymer film, which shows that the synthesis of the tin antimony oxide nano polymer film does not affect the structures of the tin antimony oxide and the polyvinyl alcohol film.
Example 2
The difference between this example and example 1 is: the volume of antimony trioxide powder is 0.5g, the volume of sulfuric acid is 10mL, the volume of hydrogen peroxide is 50mL, and the volume of ultrapure water is 35mL when preparing the tin oxide antimony powder, the mass of the tin oxide antimony powder is 10mg, the volume of the ultrapure water is 480 muL, and the volume of triethylamine is 20 muL when preparing the tin oxide antimony dispersion liquid.
Example 3
The difference between this example and example 1 is: the volume of sulfuric acid is 5mL, hydrogen peroxide is 20mL, ultrapure water is 13mL when preparing the tin antimony oxide powder, the mass of the tin antimony oxide powder is 5mg when preparing the tin antimony oxide dispersion liquid, the volume of the ultrapure water is 490 mu L, and the volume of triethylamine is 10 mu L.
Example 4
The difference between this example and example 1 is: the polyvinyl alcohol solution used in the synthesis of the tin antimony oxide polymer film was 250. mu.L.
Example 5
The difference between this example and example 1 is: the polyvinyl alcohol solution used in the synthesis of the tin antimony oxide polymer film was 1000. mu.L.
Example 6
The difference between this example and example 1 is: triethylamine was not used in the preparation of the tin antimony oxide dispersion.
Example 7
The difference between this example and example 1 is: the mass of the tin antimony oxide powder when preparing the tin antimony oxide dispersion was 150 mg.
Comparative example
The difference between this example and example 1 is: without preparing tin antimony oxide nano-particles, 5g of polyvinyl alcohol and 500 mu L of ultrapure water are used for directly synthesizing pure polyvinyl alcohol polymer film
It can be seen from fig. 4 to 6 that compared with the common glass coated with the polyvinyl alcohol film, the tin antimony oxide coated Low-E glass has better absorption and reflection effects on ultraviolet light and infrared light, and has little influence on visible transmission. And with the increase of the quantity of tin oxide antimony, the absorption and reflection effects of the Low-E glass on ultraviolet light and infrared light are enhanced, and the influence on the transmittance of visible light is small, which proves that the tin oxide antimony coated Low-E glass has good Low-radiation performance.
