Abstract

The invention discloses a method for synthesizing a nano Cu-MOF bacteriostatic agent in a water phase, which comprises the following steps: dissolving an ampholytic surfactant in water at room temperature to obtain an ampholytic surfactant aqueous solution; adding a metal salt into the ampholytic surfactant aqueous solution, uniformly conducting stirring, adding an organic carboxylic acid ligand powder, and uniformly conducting mixing to obtain a turbid liquid; and carrying out hydrothermal reaction on the turbid liquid at the temperature of 100-140 DEG C for 24-36 hours, and conducting washing and drying to obtain the nano Cu-MOF bacteriostatic agent. The method overcomes the technical difficulties that the traditional MOF material synthesis needs an organic solvent, the operation is tedious, and the large-scale industrial production is difficult. The material is green and environment-friendly, is slowly released for inhibiting bacteria by virtue of Cu ions, has efficient antibacterial capability on gram-negative bacteria and gram-positive bacteria, is high in antibacterial property and lasting in effect, and can be widely added to antibacterial fabric production of masks, protective clothing and the like.

Description

technical field [0001] The invention relates to the technical field of preparation of antibacterial materials, in particular to a method for synthesizing a nanometer Cu-MOF antibacterial agent in an aqueous phase. Background technique [0002] Masks and protective clothing are hygienic products and are widely used in hospitals and factories to filter the air entering the mouth, nose and skin, and prevent harmful gases, droplets and bacteria from entering the human body. Traditional masks are mainly composed of fiber non-woven fabrics and filter-type polypropylene melt-blown fabrics. The middle layer of melt-blown fabrics is used to filter bacteria. The filtration efficiency is not high and most of them are disposable products. High-efficiency antibacterial materials for protective clothing are very necessary. [0003] In recent years, metal-organic frameworks (Metal-Organic Frameworks, MOF) are a new type of organic-inorganic hybrid periodic network materials with high spec...
