“…The results demonstrated that the peak of heat release rate (PHRR) of EP/ P-MnMo 6 -4 nanocomposites was reduced by 41% and the char yield increased significantly, and CO and smoke emissions were also greatly suppressed. In particular, the addition of ultra-thin layered nanomaterials can increase the viscosity of a polymer and form an insulating char layer during the combustion process, thereby slowing the oxygen overflow rates and reducing the amount of combustible gas (Kong et al, 2018b, Asabina et al, 2019, Kong et al, 2019b. For example, the hybrid NiFe-LDH-MoS 2 was prepared by a simple self-assembly method and blended into EP to prepare EP/NiFe-LDH-MoS 2 nanocomposites.…”

Synergistic effect is an effective strategy for improving the flame retardancy of epoxy resin (EP). In this work, a novel graphene oxide-cobalt nickel phosphate (GO-NiCoPO 3) is successfully synthesized, which is incorporated into an EP matrix for preparing EP/GO-NiCoPO 3 nanocomposites. The results show that the limiting oxygen index value of EP/ 4GO-NiCoPO 3 nanocomposites is as high as 30.3%, and UL-94 can reach V-1 rating. The results of micro-combustion calorimetry indicate that the total heat release value and peak of heat release rate of EP/8GO-NiCoPO 3 nanocomposites are decreased by 41.9 and 23.8% compared with those of pure EP. This is mainly due to the synergistic barrier effect of GO and NiCoPO 3 , which together have their own advantages. Meanwhile, EP/GO-NiCoPO 3 nanocomposites can form a dense char layer during the burning process and improve the thermal stability of EP/GO-NiCoPO 3 nanocomposites.
