Résumé :	Ferrous disulfide (FeS2) nanocrystals were synthesized via a simple hydrothermal reaction. The FeS2 nanocrystals were then combined in intumescent flame-retardant ethylene―vinyl acetate (EVA/IFR) systems. Thermogravimetric analysis data indicate that the addition of FeS2 into the EVA/IFR composite can improve the char yields. Cone calorimeter results reveal that FeS2 and IFR can clearly change the decomposition behavior of EVA and form a char layer on the surface of the composites, consequently resulting in efficient reduction of the flammability parameters, such as the heat release rate, total heat release, and so on. Moreover, significant improvements are obtained in the limited oxygen index and Underwriters Laboratories 94 ratings. Laser Raman spectroscopy of residual char shows that the ordered carbon is increased with the addition of FeS2. Scanning electron microscopy demonstrates that FeS2 can help the EVA/IFR system form a dense char layer. The results of dynamic mechanical thermal analyses reveal that FeS2 can increase the glass transition temperature and the storage modulus of EVA/IFR. The mechanism is also proposed in this paper.
