Mechanical and flammability properties of graphene reinforced compatibilized poly(lactic acid) / poly(butylene adipate-co-terephthalate) nanocomposites

Graphene nanoplatelets (GNP) reinforced, glycidyl methacrylate (GMA) compatibilized blends of PLA/PBAT nanocomposites were prepared by melt extrusion followed by injection molding. GMA act as compatibilizer with contents of 3, 5 and 8 parts per hundred (phr) were added to the base formulation PLA/PB...
