The effect of graphite nanoplates on the thermal degradation and combustion of polyethylene

The results of cone calorimetric tests lead to traditional conclusion that formation of GNP protective shield plays a key role in the mechanism of flame retardation for PE-GNP nanocomposites. On the other hand, the decrease in PE-GNP nanocomposites combustibility can also be a result of the reduction in the diffusion rate of the degradation products in the liquid pyrolysis phase and gaseous phase of combustion.
