Embodiment 1

[0037]Embodiment 1: a kind of mountain cherry tissue culture and rapid propagation method, the method may further comprise the steps:

[0038] (1) Surface treatment of monocrystalline silicon substrate. Select a single crystal silicon substrate with a size of 10mm*10mm, place the substrate in a concentrated sulfuric acid solution, and use an ultrasonic cleaner to clean it for 10 minutes. After taking out the substrate, rinse it with deionized water and then put it into deionized water for ultrasonic cleaning for 10 minutes. Take out the substrate again and dry it in nitrogen gas. Bake in the oven to remove moisture and static electricity on the surface of the substrate;

[0039] (2) Ultrathin AAO template transfer. After the single crystal silicon substrate is cleaned, a porous anodic aluminum oxide film (AAO) is prepared, with a size of 260nm in diameter, 450nm in spacing, and 200nm in thickness. Slowly spread the polymethacrylate supporting layer (PMMA) auxiliary carrier p...

Abstract

The invention discloses a preparation method of a nano Ag-Zn double-layer lattice coating. The method comprises the following steps: carrying out surface treatment on a monocrystalline silicon substrate; transferring an AAO film to the substrate for laminating to form a target substrate; installing the target substrate at the bottom of an instrument tray, and adjusting a workbench to enable the target substrate and the central axis of a sputtering zinc target to coincide and keep parallel; sputtering a zinc dot matrix and a silver dot matrix; and tearing off the AAO film. The prepared coatinginhibits growth and propagation of bacteria such as escherichia coli and staphylococcus aureus, has a promotion effect on division and proliferation of damaged cells, is beneficial to healing of celltissues in wounds, and is in an Ag-Zn mixed dot matrix with spherical unit elements; the surface is regular, smooth and highly ordered; Ag ions and Zn ions are uniformly distributed; and the coating is of a hydrophobic structure, has a self-cleaning function and is not prone to adhesion and breeding of the bacteria.

Description

technical field [0001] The invention belongs to the technical field of coating preparation, and relates to a preparation method of a nanometer Ag-Zn double-layer lattice coating. Background technique [0002] Human society has recognized the antibacterial properties of silver materials since ancient times, and began to use silver materials for food toxicity testing or food storage. Research has found that the bactericidal efficiency of silver is related to its surface area. By increasing the surface area, the release of silver ions can be increased and the bactericidal ability can be greatly improved. Nowadays, as a kind of antibacterial material with smaller particle size and higher purity than simple silver, nano silver material has stronger antibacterial ability, high temperature resistance, safety and other advantages than simple silver in terms of antibacterial performance, and has higher economic efficiency. value. At the same time, nano-zinc also has an inactivation...
