Bulk MoS2 was chemically exfoliated and functionalized with a long alkyl amine (octadecylamine, ODA) and subsequently used as a component in the preparation of an (ODA)–MoS2/MgCl2/TiCl4 catalyst through a coagglomeration method. After in situ ethylene polymerization, flake shape polyethylene (PE)/ODA–MoS2 nanocomposites were obtained, and the ODA–MoS2 fillers were well dispersed in the PE matrix with strong interfacial adhesion. Additionally, the thermal stability and mechanical properties of PE were significantly enhanced by incorporation of the ODA–MoS2 fillers. Therefore, the in situ polymerization approach proposed here will open a new and exciting avenue for the development of transition metal dichalcogenide reinforced polyolefin nanocomposites.
