Rapid preparation of novel hybrid MoS2@Ag@PA with core–shell structure for enhancing fire safety and other critical properties of EVA composites

This paper introduces a novel hybrid material, MoS 2 @Ag@PA, with a core–shell structure aimed at improving the fire safety and critical properties of ethylene vinyl acetate (EVA). The incorporation of 2% of this hybrid material results in a remarkable enhancement in both thermal conductivity and tensile strength of EVA composites, increasing by 52.4% and 22.6%, respectively. Furthermore, the inclusion of 2% of this material leads to a significant reduction in the peak of heat release rate, total heat release, and total smoke production of the EVA composites by 36.2%, 28.1%, and 29.7%, respectively, compared to pure EVA. This indicates a substantial improvement in fire safety, mechanical properties, and thermal conductivity of the EVA composites. The enhanced flame retardancy of the EVA composites is primarily attributed to the synergistic effect of various substances within the hybrid material. Therefore, the design of these hybrids presents a promising approach to enhance the overall performance of EVA.
