PAPER STRONGER THAN STEEL
Scientists at the University of Technology in
Sydney have been able to make a new kind of material that is lighter, has a
lower density, it's stiffer and stronger even than steel. This material is not
only one of those discoveries that end up as a dead letter. It is the paper and
provided the hopes and expectations of scientists, it could experience a wide
use.
It is a graphene paper, which is made
of several single-hexagonal sheets of carbon that is chemically reformed from
graphite. In comparison with steel, graphene paper is six times lighter, it's
twice as strong, there are six times less dense, 10 times the tensile strength
and 13 times greater flexibility than steel.
Because it is a graphene, this paper has some
interesting electrical, thermal and mechanical properties. But what is perhaps
the most important thing is that its production is neither difficult nor
expensive. This means that the possibility of its application in industry is
almost unlimited, like the automobile industry, or aircraft, who would become
easier and more economical then ever.
