Embodiment 1

[0028] 1.1 Heat dodecylamine to 60°C and stir until it becomes liquid. Take 3 mL of liquid dodecylamine and mix it with 1 mL of oleic acid. The resulting mixture is set aside; weigh 0.5 mmol anhydrous zinc acetate and add it to 6 mL In the purified ethylene glycol, stir to obtain a solution, then add a mixture of dodecylamine and oleic acid, mix and stir evenly, and obtain a yellow transparent solution;

[0029] 1.2 Under the protection of nitrogen, the temperature of the yellow transparent solution was raised to 130 °C at a heating rate of 4 °C / min, and the reaction was refluxed for half an hour;

[0030] 1.3 After the reaction, add 10 mL of n-hexane to the reaction solution, stir well, then add 10 mL of ethanol and centrifuge. The product was obtained after repeating this step three times. The morphology of the obtained zinc oxide is as follows figure 2 As shown, it can be seen from the figure that the resulting zinc oxide products are all three-dimensional flower-shaped,...

Abstract

The invention discloses a preparation method of a three-dimensional flower-like zinc oxide nanometer material and an obtained product. The method comprises the following steps: mixing anhydrous zinc acetate and ethylene glycol to obtain a transparent solution, adding a mixture of lauryl amine and oleic acid into the transparent solution, and uniformly mixing so as to obtain a precursor solution; raising the temperature of the precursor solution to be 130-140 DEG C under inert gas shielding so as to carry out a reflux reaction, performing centrifugal separation and washing after reaction completion, thereby obtaining the zinc oxide nanometer material, wherein the zinc oxide nanometer material is in the shape of a three-dimensional flower. The process disclosed by the invention is simple and convenient in process flow and short in reaction time, and the obtained product has the flower shape, looks like half a calliandra flower, is controllable in morphology and adjustable in size, has excellent application prospects in the fields of new energy materials and sensing and can serve as an additive of a high-end sun and skin care product.

Description

technical field [0001] The invention relates to a preparation method of a zinc oxide nanometer material with a three-dimensional flower-like morphology and the obtained three-dimensional flower-like zinc oxide nanometer material, belonging to the technical field of semiconductor preparation. Background technique [0002] Zinc oxide is a wide bandgap n-type semiconductor material. Nano-zinc oxide has unique properties that bulk materials do not have, such as small size effect, surface effect, volume effect, and macroscopic tunnel effect. These special effects make nano zinc oxide have good application prospects in optics, electricity, magnetism, thermodynamics and so on. In particular, nano-zinc oxide has unique photoelectric properties, anti-ultraviolet radiation and antibacterial properties, making it an important research object in many fields such as chemical industry, biomedicine, and cosmetics manufacturing. [0003] Zinc oxide with different microscopic morphology can...
