Abstract

This report described a facile process for the preparation of 2D/0D MoS₂-SiO₂ hybrids using a simple in situ growth method, with the purpose of promoting the dispersion of MoS₂ in polymer matrices and improving the properties of polymer materials. FTIR, XPS, TGA and TEM measurements were performed to characterize the structure and morphology of the synthesized hybrids which were then introduced into epoxy to reduce flammability. The hybrids dispersed well in the epoxy matrix. No obvious agglomerations were observed. In comparison with those of neat epoxy, the incorporation of a low loading of MoS₂-SiO₂ hybrids resulted in significant decrements in heat release rate, total heat release and volume of toxic effluents released during combustion, which indicated that the fire hazards of epoxy composites were strongly reduced. The good dispersion, labyrinth barrier effect and the catalytic effect of MoS₂-SiO₂ hybrids on char formation may contribute to the observed decrease in the flammability of epoxy resin.
