Embodiment Construction

[0018] The substrate can be metal products such as aluminum, copper, iron, aluminum alloy, stainless steel, etc., or non-metallic products such as plexiglass. By preparing an aluminum ion film on the surface of the substrate, the different crystal planes of silver are changed when participating in the silver mirror reaction. growth rate, thereby inducing the growth of the flaky silver nanosheet structure, and the resulting nanosheet structure is maintained due to the growth advantage of longer nanosheets. When the substrate contains aluminum metal, the surface of the substrate can be treated with an acidic solution to form an aluminum ion film; when the substrate does not contain aluminum metal, a layer of aluminum can be placed on the surface of the substrate first, and then treated with an acidic solution. An aluminum ion film is formed on the surface of the substrate. Wherein, the acid solution can be hydrochloric acid, nitric acid, etc., and the concentration is preferably...

Abstract

The invention relates to process for preparing sliver-nanometer anti-bacteria material. The process comprises that an aluminum ion membrane is prepared on the surface of a substrate which is subsequently soaked into silver mirror reaction liquid, and then the substrate is taken out. The scheme employs that the aluminum ion membrane is prepared on the surface of the substrate, which enables the substrate to be covered with aluminum ion, and silver mirror reaction liquid is employed to produce aluminum hydroxide in ammoniated silver solution, which changes the growth velocity of different crystal surfaces of the silver, thereby inducing the growing of flaky silver nanometer slice structure, accomplishing the preparation of silver nanometer slice in a short time, and simplifying the industrial art. As the longer nanometer slice has growth vantage, the achieved nanometer slice structure is enabled to be preserved, thereby guaranteeing the regulation of the silver nanometer structure in silver nanometer anti-bacteria materials.

Description

technical field [0001] The invention relates to a method for preparing an antibacterial material, in particular to a method for preparing a silver nanometer antibacterial material. Background technique [0002] Inorganic antibacterial materials are mainly divided into three categories. The first category is photocatalytic inorganic antibacterial materials, such as TiO2, ZrO2, V2O3, ZnO, CdS, SeO2, GaP, SiC, etc. They can generate conductive electrons and valence band holes under light conditions. The holes attract electrons, have oxidizing ability, and have strong reactivity. They can react with H2O or OH ions adsorbed on the surface to form strong oxidizing properties. It can kill cells by virtue of the strong oxidative properties of hydroxyl groups, and can penetrate the cell membrane, destroy the membrane structure, and degrade the toxins produced by the cells. The second category is metal ion metal oxide inorganic antibacterial materials. Such materials are mainly sil...
