Chinese scientists predicted the existence of a new type of graphene

The calculations of Chinese scientists have shown the possibility of the existence of an unusual version of graphene, whose atoms form a grid of irregular pentagons. Penta-graphene, as the researchers proposed to call it, is also a structure one atom thick, but it has several advantages over its standard relative.

In ordinary graphene, atoms form a grid of regular hexagons. Penta-graphene should be fairly stable, while its strength is projected to exceed the strength of standard graphene. It must also withstand high temperatures of up to 730 degrees and be a natural semiconductor. Ordinary graphene is a conductor, and making a semiconductor from graphene is a non-trivial matter.

Another interesting feature of penta graphene is its belonging to auxetiks . Conventional materials expand in the direction of their stretching. Auxetics under tension expand perpendicular to this direction. Penta-graphene should expand in both directions.

One of the authors of the study, Quen Wong from Peking University, believes that such unusual properties will allow Penta-graphene to find application in completely different areas, from electronic circuits to body armor. As well as in nano-electronics, biomaterials and space technologies.

Unfortunately, this material exists only in the calculations. A team of scientists is in search of a suitable group of experimenters, with the help of which they can get it in the laboratory.
