As a new kind of multi-functional inorganic material, nanometer magnesium oxide has a broad application prospect in many fields. With the destruction of human living environment, new bacteria and bacteria emerge one after another, and human urgently needs a new kind of efficient antibacterial material, nanometer magnesium oxide has shown a unique advantage in the field of antibacterial.
Studies have shown that the presence of high concentration and high reactive oxygen species on the surface of nanometer magnesium oxide has strong oxidization, and nanometer magnesium oxide particles can produce destructive adsorption, and may also destroy the cell membrane of bacteria. Such antibacterial mechanism can overcome the deficiency of silver antibacterial agent's slow action, easy to change color and titanium dioxide antibacterial agent's need for ultraviolet irradiation.
The object of this study is to study the antibacterial properties of nanometer magnesium hydroxide prepared by liquid phase precipitation and calcined by nanometer magnesium hydroxide.
The purity of nanometer magnesium oxide prepared by this process can reach more than 99.6%, the average particle size is less than 40 nanometers, the particle size distribution is uniform, easy to disperse, the antibacterial rate of e. coli and staphylococcus aureus can reach more than 99.9%, which has a broad application prospect in the field of broad-spectrum antibacterial.
