Carbon nanotube has shown significant flame retardancy in cone calorimetric tests. The network structure can improve the melt viscosity of polymer nanocomposites and con?ne the thermal movement of polymer chains. Besides, the network structure can efficiently improve the barrier character to the evolution of ?ammable volatiles and the ingress of oxygen to the condensed phase. Therefore, ?ame retardancy of the nanocomposites is signi?cantly improved. However, they often fail traditional flammability tests such as limited oxygen index (LOI) and UL-94. The combination of carbon nanotube with conventional flame retardants or other nano-fillers lead to synergistic effects on flame retardancy. Very promising developments in the synergy aspects are then expected and efforts should be made in this direction.
