Abstract

The invention discloses a preparation method of a cuprous oxide-zinc oxide core-shell antibacterial material. The method comprises the following steps: preparing cubic cuprous oxide by a liquid phase reduction method, and coating the cuprous oxide with zinc oxide by a precipitation method to obtain the durable antibacterial core-shell antibacterial material. The material prepared by the invention combines the characteristics of N-type semiconductor zinc oxide and P-type semiconductor cuprous oxide, and the problems of sudden release, instability, short antibacterial timeliness and the like of the cuprous oxide are solved by wrapping the cuprous oxide with the zinc oxide, so that the cuprous oxide-zinc oxide core-shell antibacterial material prepared by the method has a good application prospect in the antibacterial field.

Description

technical field [0001] The invention belongs to the technical field of antibacterial material preparation, and in particular relates to a preparation method of cuprous oxide-zinc oxide core-shell antibacterial material. Background technique [0002] With the rapid development of China's economy and the continuous improvement of the living standards of the people across the country, people are paying more and more attention to healthy lifestyles. From ancient times to the present, diseases induced by pathogenic microorganisms have been threatening human health. Even in today's rapidly changing medical conditions, research on antibacterial materials that control and eliminate the growth and reproduction of harmful bacteria is still an important issue that is closely related to human health. Work. [0003] Among antibacterial materials, inorganic antibacterial materials have become a hot spot in the research and application of antibacterial materials due to their stable proper...
