Problems solved by technology

However, if the photoelectric device is covered by dust, the photoelectric conversion efficiency will be greatly reduced, which will bring a lot of trouble to the practical application.
However, there have been no reports of superhydrophobic antimony sulfide coatings

Embodiment 1

[0023] The preparation method of embodiment 1 superhydrophobic antimony sulfide coating, comprises the steps:

[0024] Weigh 0.5mmol of antimony trichloride and 2mmol of thiosemicarbazide and dissolve it in 30mL of ethylene glycol (EG) solvent, place the solution in a long-necked flask, and react for 15 minutes at a microwave intensity of 800W. After the product obtained was centrifugally washed to remove the residual solvent, it was then ultrasonically dispersed in 15 mL of absolute ethanol, and the dispersion was completely spread on an ordinary glass sheet, and rotated at a speed of 4000 rpm for 30 seconds to make the obtained antimony sulfide product uniform Scattered on the substrate, repeated 10 times to prepare antimony sulfide coating. Finally, soak the coating in 10mmol / L stearic acid ethanol solution for 60 minutes, take it out and dry it at 120°C for 2 hours to obtain the superhydrophobic antimony sulfide coating.

Embodiment 2

[0029] The preparation method of embodiment 2 superhydrophobic antimony sulfide coatings, comprises the steps:

[0030] Weigh 1mmoL of antimony trichloride and 1mmol of thiosemicarbazide and dissolve them in 15mL of diethylene glycol (DEG) solvent, place the solution in a long-necked flask, and react for 10 minutes at a microwave intensity of 800W. After the product obtained was centrifugally washed to remove the residual solvent, it was then ultrasonically dispersed in 15 mL of absolute ethanol, and the dispersion was completely spread on the ITO sheet, and rotated for 30 seconds at a speed of 2000 rpm, so that the obtained antimony sulfide product was evenly dispersed On the substrate, the antimony sulfide coating was obtained by repeating 30 times. Finally, soak the coating in 50mmol / L stearic acid ethanol solution for 30 minutes, take it out and dry it at 100°C for 6h to obtain the superhydrophobic antimony sulfide coating. The water contact angle of the coating surface o...

Embodiment 3

[0031] The preparation method of embodiment 3 superhydrophobic antimony sulfide coatings, comprises the steps:

[0032] Weigh 1.5mmol of antimony trichloride and 4mmol of sodium thiosulfate and dissolve in 50mL of triethylene glycol (TEG) solvent, place the solution in a long-necked flask, and react for 30 minutes at a microwave intensity of 800W. After the product obtained was centrifugally washed to remove the residual solvent, it was then ultrasonically dispersed in 20 mL of absolute ethanol, and the dispersion was completely spread on the FTO sheet, and rotated for 30 seconds at a speed of 5000 rpm, so that the obtained antimony sulfide product was evenly dispersed On the substrate, the antimony sulfide coating was obtained by repeating 30 times. Finally, soak the coating in 1 mmol / L ethanol stearic acid solution for 120 minutes, take it out and dry it at 80°C for 8 hours to obtain the superhydrophobic antimony sulfide coating. The water contact angle of the coating surfa...

Abstract

The invention discloses a preparation method of a super-hydrophobic antimony sulfide coating. The preparation method is characterized by comprising the following steps of: dissolving antimony trichloride and a sulfur precursor in a polyhydric alcohol solvent, reacting under a microwave condition, carrying out centrifugal washing on a product to remove a residual solvent, then carrying out ultrasonic dispersion in an absolute ethyl alcohol, carrying out spin-coating of dispersion liquid on a base material to obtain a uniform coating, finally steeping the coating in a stearic acid alcohol solution, taking and drying to obtain the super-hydrophobic antimony sulfide coating. The preparation method disclosed by the invention has the advantages of simple process, easiness in operation, good repeatability and suitability for mass production of super-hydrophobic coating.

Description

technical field [0001] The invention relates to a preparation method of a superhydrophobic antimony sulfide coating, which belongs to the technical field of functional materials. Background technique [0002] Superhydrophobic coating refers to the surface on which the contact angle of water droplets is greater than 150°, and the rolling angle is less than 10°. This type of coating is similar to the surface of lotus leaves, and water droplets have low adhesion on it and are easy to roll off. Therefore, it can take away the dust on the surface and has a self-cleaning effect. Generally, the preparation of superhydrophobic coatings needs to meet two conditions: one is to make the surface of the coating have a micro-nano double microstructure similar to lotus leaves, and the other is that the surface of the coating needs to be modified with low surface energy substances. [0003] Superhydrophobic coatings involve polymer materials, inorganic non-metallic materials and metal mate...
