A new way to quickly synthesise carbon nanofibers for microelectronics developed in Omsk

Scientists at the Omsk Scientific Centre (OSC) of the Siberian Branch of the Russian Academy of Sciences have for the first time in the world used a pulsed beam of charged particles for rapid production of carbon nanofibers on the surface of inexpensive polymers. The method will allow to obtain cheaper materials for manufacture of flexible electronics elements, informed Vladimir Kovivchak, one of the authors of the study and a senior researcher at the Nanostructured Composite Carbon Materials Sector of the OSC SB RAS.

The new technology, the scientist said, makes it possible to grow nanostructures 10 million times faster than existing methods. «The rate of growth of nanofibres using our method with a single irradiation can reach 160 micrometers per microsecond, which is 10 to the power of 7 times greater than growth rate of nanostructured carbon with the use of existing methods of synthesis,» Kovivchak explained.

Moreover, the method makes it possible to produce nanofibers on the surface of a thin layer of polymer applied to a material with a low melting point, even to paper, which is not possible with the use of other techniques, since the latter require temperatures above 500 degrees Celsius.
