Flame retardation mechanism of fullerenes

The SEM image of the residue of the PP/Ceo sample showed that Ceo crystals only aggregated rather than forming a compact and continuous network. Thus, it was not the char residue that was responsible for the enhanced thermal stability and improved flame retardancy of PP/Ceo nanocomposites. Because the char residue could not confer flame retardancy on polymers, possible reasons may be concealed in the primary state or in the heating or combustion of polymer materials. 

2 Relationship between flammability properties and rheological behavior 

To clarify the flame retardation mechanism, rheological measurements were introduced to investigate the viscoelastic behavior of the nanocomposites. First, the viscoelastic behavior
