A facile method for preparing polyethylene (PE)/octadecylamine-functionalized MoS2 (ODA-MoS2) nanocomposites through in situ polymerization with an ODA-MoS2-MgClTiCl4 catalyst was developed. The catalyst was synthesized simply by the treatment of ODA-MoS2 with a Grignard reagent, followed by anchoring of a TiCl4 catalyst. The resulting catalyst exhibited higher activity toward ethylene polymerization than did an ODAMoS2-free catalyst. After polymerization, the resultant PE/ODA-MoS2 nanocomposites reproduced the catalyst morphology, showing a flaked morphology. In addition, the thermal stability and mechanical properties of PE were significantly enhanced by the introduction of ODA-MoS2 fillers. These properties could result from the good dispersion and strong interfacial adhesion of ODA-MoS2 fillers and the PE matrix.
