Enhanced thermal and fire retardancy properties of polypropylene reinforced with a hybrid graphene/glass-fibre filler
The thermal stability and flame retardancy properties of polypropylene (PP) nanocomposites containing graphene nanoplatelets (GNPs), glass fibres (GFs) or a hybrid mixture of the two fillers were investigated. The GNPs enhanced the thermal stability of the nanocomposites by at least 48 °C as a resul...

| description | The thermal stability and flame retardancy properties of polypropylene (PP) nanocomposites containing graphene nanoplatelets (GNPs), glass fibres (GFs) or a hybrid mixture of the two fillers were investigated. The GNPs enhanced the thermal stability of the nanocomposites by at least 48 °C as a result of the nanoconfinement of the polypropylene chains and the prevention of the emission of the gaseous molecules during decomposition. Pyrolysis combined with gas chromatography and mass spectroscopy showed that the decomposition mechanism of the polymer was not altered by the presence of the nanofillers and the alkenes that comprised of 3n carbon atoms were the main degradation products. Cone calorimetry tests revealed a significant delay of the ignition under irradiation with the addition of GNPs to the PP. Furthermore, the GNPs lowered the combustion rate of the PP due to the formation of a carbonaceous protective layer that acted as a barrier to heat and mass transfer. The lightweight materials prepared show promising results for applications where high thermal stability along with fire retardancy are a prerequisite, such as parts for vehicles or aircraft. |
