Graphene is a carbon material in which atoms united in a crystal lattice to form a layer only one atom thick. Graphene discovered eleven years ago two native of Russia – Konstantin Novoselov and Andrei Game. For his opening specialists who left to live in the UK and the Netherlands accordingly, received in 2010 the Nobel Prize for physics.

No wonder graphene is called the material of the future. His plan use in medicine, science, astronautics, construction and many other industries. One of the striking features of graphene is its incredible strength. Material sheet area one square meter can easily withstand four kilograms of weight, and this despite the fact that the sheet thickness is only one atom! Thus, graphene is about a hundred times stronger than steel. He also Differs in high conductivity, transparency and flexibility. IN present scientists intend to prove that the material impervious to the vast majority of gases and liquids, although water does not belong to them, because graphene, perhaps, it will be possible use as its filter.
But first of all, it will become an indispensable material for production of smartphones and other portable gadgets. Strength Graphene will give devices greater durability. Moreover, engineers have long wanted to create a smartphone that can be fold like a sheet of paper, and graphene for the first time gave a chance for implementation such projects. The material can be used for production batteries – such batteries should have a large capacity and recharge in just a few minutes. Already made first graphene solar panels that exhibit higher performance, however, and much higher cost for Compared to traditional.
Unfortunately, graphene is still too expensive material. The main way to obtain it is by chemical precipitation from gas phase when graphene is deposited on an expensive substrate from copper, requiring complex pre-treatment. Not by chance scientists around the world are looking for ways to reduce the cost of production of grephene. ABOUT Researchers have already boasted some achievements in this area. Poland (1914), Great Britain (this summer), over this scientists from many world corporations work as a problem.
And physicists from the University of Glasgow just the other day reported that they developed a much cheaper manufacturing method graphene. The Scots have found an inexpensive substitute for copper, which costs just one dollar per square meter. While traditional copper substrate costs one hundred and fifteen dollars per sheet similar area. Moreover, expensive copper accounted for specially process what made the graphene manufacturing process even more costly.
Thus, graphene may soon become a hundred fifteen – one hundred twenty times cheaper, and then by all means the real graphene revolution will come.
