Abstract

A novel exfoliated-MoS₂ (EMoS₂)–MgCl bi-supported Ziegler-Natta catalyst was synthesized by the reaction of Grignard reagent and EMoS₂, followed by anchoring with TiCl₄. The tendency of the individual EMoS₂ layers to aggregate was prevented by covering them with solid-state Ziegler-Natta catalyst. The resultant catalyst was applied to ethylene polymerization, forming polyethylene (PE)/EMoS₂ organic-inorganic hybrid nanocomposites. The resultant products had a flake-shape morphology, with EMoS₂ well dispersed in the PE matrix. In addition, the thermal stability and mechanical properties of PE were significantly enhanced by the introduction of EMoS₂.
