Embodiment Construction

[0006] A preparation method of nanometer copper oxide antibacterial agent, is characterized in that, adopts microwave-assisted method, specifically comprises the following steps:

[0007] 1) Deionized aqueous solutions of copper nitrate and urea were prepared respectively, the concentration of the copper nitrate solution was 0.1M, and the concentration of the urea solution was 0.4-0.6M;

[0008] 2) Take an equal volume of the above-mentioned copper nitrate solution and urea solution in a three-necked flask, place the three-necked flask in a microwave oven, and under magnetic stirring, set the power to 300-900W and react at 50-100°C for 15-60 minutes to obtain green cloudy liquid;

[0009] 3) Centrifuge the turbid liquid obtained in step 2), wash the separated solid with deionized water and absolute ethanol for 1 to 4 times, and then place it in a constant temperature drying oven at 80°C for 2 hours to obtain Basic copper carbonate precursor;

[0010] 4) Put the basic copper ...

Abstract

The invention belongs to the field of inorganic material, in particular relates to a preparation method of cupric oxide nanoparticle which adopts a microwave assisted method to first prepare a precursor, then carries out roasting at appropriate temperature, obtains cupric oxide nanoparticle with the structure of plate shape and tests the antibiosis performances of an inhibition zone for the powder of the cupric oxide nanoparticle. That the cupric oxide nanoparticle with the structure of special plate shape has good antibiosis effect on staphylococcus aureus and hay bacillus is discovered. The preparation method of the invention has the advantages of cleanness, high efficiency, low energy consumption, little pollution and being capable of synthesizing nano materials with high purity and uniform distribution in limited time, etc., thus starting a new field for the synthesis of nano materials.

Description

technical field [0001] The invention belongs to the field of inorganic materials, and in particular relates to a preparation method of a nanometer material, in particular to a preparation method of a high-efficiency nano-copper oxide antibacterial agent with a plate-like structure. Background technique [0002] Copper oxide is a multifunctional fine inorganic material with a wide range of uses. It has unique electrical, magnetic, and catalytic properties. It has been used in catalysis, printing and dyeing, glass, ceramics, and medicine for many years. When the particle size of copper oxide is reduced to the nanometer level, its properties will be more unique and its application will be more extensive. The preparation method of nanomaterials will affect the microstructure of the material, and then directly affect the properties of the material. Therefore, different preparation methods are continuously researched and developed in order to obtain nanomaterials with ideal struc...
