British researchers have developed a graphene paint that can protect surfaces from corrosion.
Recent findings by researchers at the University of Manchester show that graphene can be used as a protective layer for packaging and long-term protection of foods.
Graphene is a monolayer of carbon atoms that converts to graphene oxide if it has oxygen groups.
It is widely used in the pharmaceutical, chemical and electronics industries
If graphene is applied as a paint on the surface, it forms a strong and non-corrosive layer that has several applications in industry. Graphene oxide paints can be applied to a variety of surfaces, from glass to metals and even bricks.
After a chemical treatment, this coating acts like graphite and will have good chemical and thermal stability. However, it is mechanically stronger than graphene, the strongest material known to date.
This research team had previously shown that graphene oxide multilayer films act like molecular sieves if dried under vacuum and re-exposed to water vapor, and that small molecules could be filtered to dimensions smaller than a certain limit. This finding by researchers could have a dramatic effect on water purification and purification.
A recent paper by researchers at the University of Manchester in the journal Nature Communications shows that graphene can be activated to block the spaces between layers of graphene oxide and prevent molecules from passing through; therefore, gases, fluids and chemicals will not be able to pass through these layers
In this study, researchers showed that the surface of copper sheet can be coated with this graphene paint and used as a storage tank for corrosive acids.
The exciting achievements of this project have attracted the attention of several private companies to work with the University of Manchester to build new anti-corrosion coatings as part of this collaboration.
According to the researchers, graphene paint has a great chance to become a revolutionary product in industry to protect industrial equipment from airborne contaminants and corrosive chemicals.
