Abstract

The dodecanethiol-modified molybdenum disulfide (OMoS₂) was used as template to form a layered OMoS₂[sbnd]MgCl₂-supported Ziegler–Natta catalyst via a co-agglomeration method. The effects of OMoS₂ on the catalyst morphology and ethylene polymerization behavior were examined. The resultant polyethylene (PE)/OMoS₂ nanocomposites mirrored the catalyst morphology, and the OMoS₂ fillers were well dispersed in the PE matrix. In addition, the thermal stability and mechanical properties of PE were significantly enhanced by the introduction of very small amounts of OMoS₂ filler. This enhancement resulted from the good dispersion and interface adhesion of OMoS₂ and the PE matrix. Thus, this work proposes a new method for the production of high-performance PE.
