Flammability and Thermal Degradation of PMMA/Graphene Composites
Abstract:
Graphene nanoplatelets (GNP) were prepared by ball milling, and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). PMMA/GNP composites were produced by a melt process. The flammability of PMMA/GNP composite was evaluated by the cone calorimeter (Cone) and thermal degradation of the composite by thermogravimetric analyses (TGA). Cone data indicate that the incorporation of 1% GNP leads to a 12% reduction in the peak heat release rate compared to pure PMMA. The TG results show that the addition of small amount of GNP (1%) can improve thermal stability of PMMA.
