International. A group of scientists cataloged graphene as a miraculous material, a carbon allotropy that is evaluated by specialists as the possible thinnest anticorrosive coating on record. The study was published by the journal ACS Nano of the American Chemical Society and was supported by the National Science Foundation.
This research showed that, for example, copper coated by increasing simple layers of graphene by chemical vapor deposition, also called CVD (Chemical Vapor Deposition) corrodes seven times slower than bare copper, while nickel when coated by increasing multiple layers of this material makes it 20 times slower than the discovered nickel.
Dhiraj Prasai, one of the scientists involved in the study, said: "In graphene, carbon atoms are arranged like a wire mesh fence in a layer so thin that it is transparent, and with a single ounce you can cover 28 football fields."
Graphene is a simple layer of carbon atoms, often used in pencils or charcoal and provides the same corrosion protection as conventional organic coatings that are five times thicker.
Corrosion-inhibiting graphene coatings would be ideal for applications where thin layers are required such as in microelectronic components, such as interconnects, aircraft components and implantable devices.
