Method for preparing silver nano antibacterial material

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...
