An international team of the researcher led by Dr. Elton Santos from the University’s School of Mathematics and Physics has come up with super lubricity in a few layers of graphene, they also exposed h-BN known as hexagonal boron nitride. The hexagonal boron nitride is flexible as well as lighter and cheaper and they are strong like a diamond.
The discoveries uncover that the h-BN layers frame the most grounded thin encasing accessible all-inclusive and the one of a kind characteristics of the material could be utilized to make adaptable and practically unbreakable brilliant gadgets, and in addition scratch-verification paint for autos.
“We have all at some point in life stepped on a slippery surface where we have to steady our balance so that we don’t fall. In most cases, a liquid such as water or oil is the cause and this slippery state is what we describe as super lubricity, there is basically no friction on a surface”, said by Dr. Santos.
Further, he stated, “In graphene, this super lubricity state comes from atomic orbitals that compose carbon atoms. Normally, to generate friction some orbitals must overlap and heat, or some energy, must be released. Surprisingly”. Dr. Santos explained that the discovery proves that the graphene does not require this process, naturally it just on top of other layers but does not release heat.
The discoveries around the h-BN layers demonstrate that its mechanical properties are like a jewel, however, are significantly less expensive, more adaptable and lighter. It can be coordinated in small electronic circuits.
Dr. Santos said, “Our key finding is that bilayer graphene develops a super-lubricity state where no heating is generated as the layers slide on top of each other”. Further, he added, “This stretchy material could also be used in electronic devices and motor engines to make friction very low, as no heat is released”.
