Synergistic improvement of flame retardant properties of expandable graphite and multi-walled carbon nanotube reinforced intumescent polyketone nanocomposites

Flame retardant and self-extinguishing properties of composites are of importance to minimize heat release and smoke production during combustion for fire resistant polymer composites. This work presents intumescent flame retardant polyketone nanocomposites composed of multilayered expandable graphites incorporated with multi-walled carbon nanotubes. We observe a significant reduction of heat release rate, total heat release, and smoke...
