The presumptive antioxidative activity of fullerenes C60/C70, original and purified multiwalled carbon nanotubes, carbon nanofibers of platelet and herringbone structures was studied using model reaction based on a liquid-phase oxidation of cumene initiated by 2,2′-azobisisobutyronitrile. Kinetic measurements of oxidation rates clearly showed that the effect of inhibition in the model oxidative reaction in the presence of the nanoparticulated carbon samples strongly depends on the presence of metallic traces (Co, Fe, Ni). The effective rate constants for the addition of cumyl radicals (R•) to the central nervous system (CNS) have been precisely determined. The obtained kinetic data make it possible to specify the level of intrinsic antioxidative activity of the CNS and scope of their rational use in polymer composites.
Polyethylene composites appropriately filled with CNS exhibit extremely heightened thermal and thermo-oxidative stability.
