Graphene paint ultra-strong and anti-corrosion
Paint is regarded as a liquid that, once applied to a substrate, converted to a solid film, Paint is used to improve the surface properties of all metal and building properties such as corrosion resistance, durability, wettability, and adhesion. Paints, a special category of coating, are used to protect, beautify and reduce maintenance requirements, but the paint has main problem that is corrosion because it make paint useless and substrate need re-paint again and again, Corrosion in its various forms is estimated to cost the global economy $3 trillion a year. Products to protect against corrosion represent an $18 billion world market.
So research to modify paint non-stop to less corrosion and improved features, So researchers test Graphene when entering in paint material and found wonderful results, when graphene enter alone or as part of a composite, displays excellent characteristics for the coating industry.
How Graphene use to make paints:
The surface of graphene, a one-atom-thick sheet of carbon, can be randomly decorated with oxygen to create graphene oxide; a form of graphene that could have a significant impact on the chemical, pharmaceutical and electronic industries. And it use in paint materials , it could provide an ultra-strong, non-corrosive coating for a wide range of industrial applications.
Graphene oxide solutions can be used to paint a lot various surfaces ranging from glass to metals to even bricks . After a simple chemical treatment, the resulting coatings behave like graphite in terms of chemical and thermal stability but become mechanically nearly as tough as graphene, the strongest material in the world !
Manchester University has cooperated with Holland’s paints and coatings company Akzo Nobel, to investigate graphene oxide-based paints that provide protection against rust and corrosion for large metal structures, such as oil rigs, ships, tankers and bridges.
This collaboration between Akzo Nobel and Manchester University is part of a €1m partnership in corrosion research. Akzo Nobel says graphene oxide could provide an ultra-strong, non-corrosive coating for a wide range of industrial applications.
For this exceptional barrier properties of graphene paint have already attracted interest from many companies who now collaborate with The University of Manchester on development of new protective and anticorrosion coatings.
And graphene reseachers think graphene the best material for a lot of purpose Dr 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.”
Dr Yang Su, the first author in this work added: “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 vapour than conventional coatings. In addition, thin layers of graphene paint are optically transparent.”
