Abstract

The invention discloses the application of nano reduced graphene oxide serving as an antibacterial material, in particular relates to the application of nano reduced graphene oxide suspension or a nano reduced graphene oxide membrane serving as an antibacterial material. The preparation method of the nano reduced graphene oxide suspension comprises the following steps of: pre-oxidation of graphite, separation of a pre-oxidized product, re-oxidation, purification of an oxidation product and reduction of the oxidation product. The nano reduced graphene oxide film is prepared by performing suction filtration on the nano reduced graphene oxide suspension by using a polyvinylidene fluoride (PVDF) membrane of which the mesh is 0.22 mu m. Through the application of the nano reduced graphene oxide serving as the antibacterial material, the nano reduced graphene oxide serving as an additive can be prepared into a product with an antibacterial property or prepared into an antibacterial coating material, which is applied to medicines and daily life.

Description

technical field

[0001] The invention relates to an antibacterial material, in particular to the application of nano-reduced graphene oxide as an antibacterial material. Background technique

[0002] With the development of microbiology, people's research and understanding of microbes are constantly improving. While making full use of beneficial microbes, they are also very vigilant against pathogenic microbes. How to prevent pathogenic microbes from invading the human body has become an urgent problem to be solved. However, in the process of preventing and controlling pathogenic microorganisms, many problems have occurred due to the extensive use of antibiotics. One of the most prominent is the emergence of a large number of drug-resistant strains of pathogenic microorganisms; at the same time, the extensive use of antibiotics has also caused serious environmental pollution, which has caused harm to human health and quality of life. How to solve these problems, people are r...
