Abstract

In order to improve fire safety of polymer materials, considering unique properties of molybdenum disulfide (MoS2), and based on nanocomposite and catalytic carbonization technology, CeMnOx-MoS2 and CeFeOx-MoS2 nanohybrids were synthesized by co-precipitation method and then incorporated into two typical polymer matrices (Thermoplastic polyurethane and Epoxy resin). The results indicate that the two kinds of nanohybrids are uniformly distributed in polymer matrix, which effectively delays thermal degradation of polymer materials and increases char residues at high temperature. Moreover, the addition of nanohybrids leads to the decreases of flammable gas, CO and smoke density during combustion of polymer composites, indicating significant improvement of fire safety performance. © 2022, Editorial Department of China Safety Science Journal.
