ULTRA-THIN CARBON FIBERS WITH DIFFERENT STRUCTURES Russian patent published in 2009 - IPC D01F9/127 B82B1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to technology of obtaining ultra-thin carbon fibers and can be used as filler material, added to tar and similar materials. Fiber contains fiber-like material, including tubular grapheme sheets, placed one upon another perpendicular to the axis of the ultra-thin carbon fiber, in which the tubular grapheme sheets have polygonal cross-sections perpendicular to the axis of the carbon fibers, where the maximum diameter of the cross-sections is between 15-100 nm, the coefficient of proportionality is not more than 10⁵, and the value I_D/I_G of the ultra-thin carbon fiber is according to Raman spectroscopy, not more than 0.1. Ultra-thin carbon fiber can improve, even in small quantities to the matrix, physical properties, such as electrical, mechanical and heat properties of the matrix, without destroying the initial properties of the matrix.

EFFECT: improving the electrical, mechanical and heat properties of the matrix, without destroying the initial properties of the matrix.
