FORMATION OF CARBON NANOSTRUCTURES DURINGIR-PYROLYSIS OF POLYACRYLONITRILE IN PRESENCEOF Fe AND Co

摘要

It is shown that IR-pyrolysis of compositions based on polyacrylonitrile andCo(C5H702)2, Fe(C5H5)2 results in formation of a metal-carbon nanocomposite inwhich nanosized particles of metal are dispersed finely in the structure of the carbonmatrix. Carbonaceous phase of this composite is a carbon-carbon nanocomposite of astructure where carbon nanoparticles (carbon nanospheres, or nanoswirls) areembedded into the main graphite-like material.
