Embodiment 1

[0037]Embodiment 1: a kind of preparation method of nanometer Ag-Zn double-layer lattice coating, this method comprises the following 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 ca...

Abstract

The invention discloses a method for preparing a nano-Ag-Zn double-layer lattice coating. The method comprises the steps of: surface-treating a single-crystal silicon substrate; transferring an AAO film to the substrate to form a target substrate; installing the target substrate At the bottom of the instrument tray, adjust the workbench so that the target substrate coincides with the central axis of the sputtering zinc target and keep them parallel; sputter the zinc lattice and the sputtering silver lattice; tear off the AAO film. The coating prepared by the invention can inhibit the growth and reproduction of bacteria such as E. coli and Staphylococcus aureus, and at the same time promote the division and proliferation of damaged cells, which is beneficial to the healing of cell tissues in wounds. The prepared coating has a round shape. Ag-Zn mixed lattice of spherical unit elements; its surface is regular, smooth and highly ordered; and Ag ions and Zn ions are evenly distributed; the coating is a hydrophobic structure, which has a self-cleaning function and is not easy to adhere to and breed 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...
