Embodiment 1

[0073] This example is used to illustrate the preparation method of the modified nano-zinc oxide material used in subsequent test examples.

[0074] (1) Get ball milling beads (50g of zirconia beads of 0.01mm) and put them into a ball milling jar with a volume of 100ml, add 0.5g nanometer zinc oxide powder and 0.5g 4-mercaptophenylboronic acid, set the ball mill line speed to 800m / min, ball milling time is 1h.

[0075] (2) Turn off the ball mill, remove the ball mill tank after 30 minutes, and take out the dispersed solution in the ball mill tank. See the photo for its appearance figure 1 , which were characterized by Fourier transform infrared spectroscopy (FTIR), such as figure 2 .

[0076] (3) The nano-zinc oxide solution coated with small molecules obtained is characterized by a transmission electron microscope (TEM), as image 3 .

[0077] In the above examples, the purity of the nano-zinc oxide raw material is 99.99%, the purity of the 4-mercaptophenylboronic acid ...

Abstract

The invention provides a modified nano zinc oxide material, and also provides a preparation method and application of the material. The specific preparation method comprises the following steps: carrying out ball milling treatment on nano zinc oxide powder and a small molecular reagent 4-mercaptophenylboronic acid to form a 4-mercaptophenylboronic acid modified zinc oxide nano material, and carrying out an antibacterial performance test on the 4-mercaptophenylboronic acid modified zinc oxide nano material to discover that the modified nano zinc oxide material has significantly enhanced antibacterial performance. The technical process is relatively simple, industrial production is easy to realize, reagents are cheap, and the micromolecule-coated nano zinc oxide solution with excellent antibacterial performance can be obtained.

Description

technical field [0001] The invention belongs to the technical field of nano-materials, and in particular relates to a modified nano-zinc oxide material, a preparation method and an application. Background technique [0002] Zinc is one of the essential trace elements for cells. Zinc exists in more than 3,000 kinds of human proteins. There are about 2–3 grams of zinc in the adult human body. Zinc deficiency can lead to problems such as anemia, growth retardation, hypogonadism and mental exhaustion. Therefore, nanomaterials developed with zinc as the basic component have inherent advantages in the field of nanomedicine due to their excellent biocompatibility. [0003] At present, zinc-containing nanomaterials are mainly zinc oxide nanoparticles, which have good application prospects in antibacterial and anticorrosion due to their low cost, good oxidation resistance and unique semiconductor characteristics. However, the biggest shortcoming of nano-zinc oxide materials reporte...
