摘要

摘要:本文报道了一种用不同尺寸分布的磁铁矿纳米颗粒修饰剥离二硫化钼纳米片的简易制备方法。所得材料已被用作聚乙烯的纳米填料，以提高其热性能和阻燃性。磁铁矿修饰的二硫化钼纳米片的掺入降低了峰值放热速率。纳米填料含量为2 wt. %的e-MoS2/Fe3O4复合材料的导热性能最好。CO排放量最低的PE/e-MoS2复合材料也含有2 wt. %的Fe3O4。与原始聚乙烯相比，所有具有剥离MoS2的复合材料都表现出更高的热性能。

Enhancement of Thermal Stability, Conductivity and Smoke Suppression of Polyethylene Composites with Exfoliated MoS2 Functionalized with Magnetite

Abstract This work reports a facile fabrication method to modify exfoliated molybdenum disulfide (e-MoS2) nanosheets with magnetite nanoparticles with various size distribution. The obtained materials have been utilized as nanofillers of polyethylene to enhance its thermal properties and flame retardance. The incorporation of magnetite modified MoS2 nanosheets leads to the reduction of the peak heat release rate. The best thermal conductivity has been noticed for composites with e-MoS2/Fe3O4 with 2 wt. % of nanofillers. The lowest CO emission was observed for the PE/e-MoS2 composite containing also 2 wt. % of Fe3O4. All composites with exfoliated MoS2 exhibited greater thermal properties in respect to the pristine polyethylene.
