Graphene is the strongest material known to man and it is a one atom thick carbon sheet which is randomly joined with oxygen atom to make grapheme oxide. It is now known that a thin coating of Graphene will serve as a chemical resistant coating which could keep food fresh and also protect metals from getting corroded by the vagaries of atmosphere.
The one atom thick carbon Graphene has immense use in the chemical, pharmaceutical and electronic industries, the University of Manchester reported.
Study leader Rahul Nair said, “Graphene paint has a good chance to become a truly revolutionary product for industries that deal with any kind of protection either from air, weather elements or corrosive chemicals. Those include, for example, medical, electronics and nuclear industry or even shipbuilding, to name but the few.”
A thin layer of Graphene oxide paint could serve as an ultra tough and non corrosive coating and could be used to cover a number of things such as metal, glass, and brick. Graphene oxide solution behaves just like graphite when it comes to chemical and thermal stability and is as strong as Graphene.
Yang Su, the first author of the study, reported, “Graphene paint can be applied to practically any material, independently of whether it’s plastic, metal or even sand. For example, plastic films coated with Graphene could be of interest for medical packaging to improve shelf life because they are less permeable to air and water [vapor] than conventional coatings. In addition, thin layers of Graphene paint are optically transparent.”
Research in the past has revealed that multiplayer films made of Graphene oxide are vacuum tight under dry and moisture free conditions. These films also act like a sieve and allow the passage of small molecules. This find can be used in the purification of water.
