摘要: Abstract A series of polycarbonate (PC)/acrylonitrile butadiene styrene (ABS) (70/30 wt.%) nanocomposites with varying concentrations (0–5 wt.%) multilayer graphene particles (GNP) were fabricated using melt extrusion process. The flammability, thermal, mechanical and morphological properties the was investigated. Cone calorimeter analysis, limiting oxygen index (LOI) UL94 flame rating tests revealed that addition GNP to PC/ABS significantly improved retardancy PC/ABS/GNP nanocomposites. As much as 30.4% reduction in peak heat release rate observed for 3 wt.% loading. maximum LOI value 26% 3wt.% content. UL-94 V-2 less dripping compared pure sample. TGA analysis showed incorporation enhanced thermal stability char yield Scanning electron microscopy nanoplatelets unidirectionally aligned parallel surface
