Carbon Nanotechnology

 

Nanotechnology operates on objects, comparable in size to atoms and measuring from 1 to 100 nm. The use of nanometre-sized particles changes our concept of what is possible in medicine, electronics and technology. Nanotechnology is one of the most promising and rapidly developing areas of science today.

Carbon nanotechnology is a technology using fullerenes, nanotubes and other similar structures (carbon framework structures). In 1997, Richard E. Smalley, R. F. Curl Jr., and Sir Harold W. Kroto received the Nobel Prize in Chemistry for their study of light fullerene molecules C60 and C70.

The three-dimensional spherical fullerene molecule has unique physical, chemical and physico-chemical properties, including:

  • • electrical (semiconductor, conductor and superconductor under certain conditions);
  • • optical (photochromic effect, change in light transmission depending on intensity);
  • • chemical (ability to form compounds with many different sorts of material, the ability to retain other substances inside the molecule and the ability to absorb free radicals);
  • • biological (fullerenes are relatively safe and inert, and yet have properties that allow the substance to create active derivatives).

This set of special properties varies depending on the type of materials with fullerenes or fulleroid fragments and provides for a very broad scope for their application.

 

The closed technological cycle used at ILIP CJSC makes it possible to produce the following types of carbon-based nanomaterials:

  • • individual fullerene C60 with substance content of 99.5% and higher, including super-pure sublimed fullerene C60;
  • • individual fullerene C70 with substance content of 98% and higher;
  • • mixture of individual C60 and C70 fullerenes with substance content of 99.5% and higher;
  • • dry extract of a mixture of heavy fullerenes with substance content of 98% and higher;
  • • fullerene soot containing 10-11% of fullerenes;
  • • washed fullerene soot, left after the extraction of fullerenes;
  • • mixture of heavy fullerenes (C76, C78, C84 and above);
  • • hydrated fullerene (fullerenol) C60(OH) n (n ~ 18-22).

 

The fullerenes and fulleroid products are used to develop new modifiers and create hi-tech materials with certain improved properties.

 

The Company has begun industrial production of carbon-based nanomaterials.
