SYNTHESIS OF CARBON NANOTUBES AND FULLERITE STRUCTURES AT PT PARAMETERS CORRESPONDING TO NATURAL MINERAL FORMATION

Abstract

At 700°C and 500 MPa fullerite multilayer formations with diameters from 200 to 800 Å were synthesized from polypropylen. The diameter of the inner cavity or channel in these structures varied from 20 to 60 Å. These formations are analogous in appearance to short, closed multilayer carbon nanotubes formed during fullerene synthesis under vacuum discharge conditions at ~5000° K.
