Graphene, as the thinnest, toughest and best conductive nano material found at present. It is a two-dimensional crystal composed of carbon atoms stripped from graphite material with only one layer of atom thickness. Known as “black gold”, it is “the king of new materials”. Scientists even predicted that graphene “will completely change the 21st century”.
Request a quoteGraphene is a two-dimensional material composed of carbon atoms, which have a large specific surface area. On the one hand, the antibacterial and antiviral ability of graphene comes from its oxidative stress, which can destroy the structure of cells and viruses; On the other hand, it can be used as the carrier of a variety of antibacterial reagents to greatly improve their uniform dispersion and antibacterial effect and reduce the cost.
Graphene materials have been used in the field of antibacterial and antiviral, and its antibacterial and antiviral ability has been verified in a variety of material systems.
The antibacterial properties of graphene oxide were studied by the Shanghai Institute of Applied Physics, Chinese Academy of Sciences. The sterilization effect reached 98.5% within 2 hours. Huazhong Agricultural University studied the antiviral performance of graphene oxide. At a low concentration of only 1.5mg/l, graphene oxide can kill 95% of the virus within 1h. In addition to pure graphene materials, graphene-loaded silver, copper, titanium dioxide and other composite antibacterial materials also show better antibacterial effects.
The South Korean global desalination research center and the National University of Singapore studied the antibacterial properties of graphene-supported silver and copper respectively, which showed more than 98% antibacterial properties. Graphene has the advantages of nonvolatilization and non-loss and has the long-term antibacterial ability.
In the application research of graphene antibacterial materials, China Aviation Development Beijing graphene Technology Research Institute has developed various graphene antibacterial composites such as polyethylene, polypropylene, and epoxy resin. Among them, the antibacterial rate of graphene polyethylene antibacterial film against Escherichia coli and Staphylococcus aureus exceeds 99.9999%, and the number of colonies can be reduced from 6.9 billion to less than 1000; The effective rate of graphene polypropylene composite meltblown cloth against coronavirus (hcov-229e) is 99.22%. At present, anti-virus mask products have been formed; Graphene epoxy resin has been developed with antibacterial efficiency of more than 99.99%. It is an important raw material for the preparation of antibacterial structure-function integrated materials. Related technologies can be used in the production of antibacterial composites or coatings.
