Russian scientists have developed a unique nanomaterial

 

Russian scientists have made an important step in the development of technologies fundamentally new materials. At the Institute of Problems of Chemical Physics, Russian Academy of Sciences have developed new methods for creating single-walled carbon nanotubes. Difficult to overestimate the importance of technology — ultra nanotubes with unique properties necessary in all industrial sectors.

Authors development awarded in Moscow as part of the international forum "High Technologies of XXI Century". The fact that carbon nanotubes are present, as they are used and how they are doing, in an interview on "Russia 24"Said the head of the research group of the Institute, Doctor of Physical and Mathematical Sciences Anatoly Krestinin.

According to him, the single-walled carbon nanotubes are cylinder, which can be obtained graphene folding and connecting edges of the cylinder is seamless. Graphene, in turn, is a mesh, like a honeycomb. Single-walled carbon nanotubes have different qualities that are "most-most," said the scientist. This is the most delicate carbon fiber. Its diameter is 30 thousand times smaller than the diameter of a human hair. This is the strongest fiber. It is 10 times stronger than carbon microfibers used in composites that are used in construction materials for aviation and space. They are lightweight, their density is less than 2 times graphite. They have the highest specific surface area of all the currently known materials. Just add a hundred-thousandth share of single-walled carbon nanotubes in a polymer to its strength properties have increased by 30-80%, said the doctor of physical and mathematical sciences.

As explained Anatoly Krestinin, all these developments are made on the basis of basic research that led to the end of the 90s at the Institute of Problems of Chemical Physics, Russian Academy of Sciences. Realizing the importance of the special properties of the nanotubes, which were discovered in 1993, has been a rapid mass influx of scholars in this area. Intensively developed methods for their synthesis and use. In 2005 there were the first in the west of the company, which began selling the product, recalled the scientist. "In Russia we first started to develop these technologies and equipment for the production of a wide range of products that use single-walled carbon nanotubes," — added Krestinin.

As to the scope of their application, it is very broad, stated Doctor of Physical and Mathematical Sciences. They are used to reinforce polymeric binders, which can be obtained from an optically transparent film which conducts an electric current. It can replace the material that is now used in the touch screens of smartphones. The film based on single-walled carbon nanotubes is several times cheaper than glass used now, they are significantly more flexible. There are other important sectors, where will find its application developed technology, summed up the head of the research group of the Institute of Problems of Chemical Physics, Russian Academy of Sciences.
