The results indicate that the addition of β-CD@SnPP obviously improve the thermal stability and residual yield of EP composites at higher temperature. When the amount of β-CD@SnPP is only 4 wt%, EP/4β-CD@SnPP composites pass V-1 rating, and LOI value is up to 30.8%. Meanwhile, β- CD@SnPP effectively suppress the heat release and reduce the smoke production of EP/β-CD@SnPP composites in combustion, and the peak heat release rate (PHRR), total heat release (THR), smoke production rate (SPR) of EP/6β-CD@SnPP composites reduce by 28.4%, 33.0% and 44.8% by comparison with those of pure EP. The good flame retardancy and smoke suppression are ascribed to the synergistic effect of excellent carbon-forming capability and fire retardancy of β-CD@SnPP.}, DOI = {10.32604/jrm.2022.019576} }
