摘要：

Here, we report a facile coagglomeration method for the preparation of graphene (G)/MgCl2- and graphene oxide (GO)/MgCl2-supported Ti-based Ziegler-Natta catalysts. The effects of the G-filler type on the ethylene polymerization behaviors and polymer properties were investigated. The morphologies of the resultant PE/G and PE/GO nanocomposites exhibited a layer-like shape and the G and GO fillers were well dispersed within the entire PE matrix. In addition, the thermal stability and mechanical properties of the PE were significantly enhanced by the introduction of a very small amount of G or GO fillers (0.02 wt%), due to the satisfactory dispersion of the G or GO in the PE matrix. Compared with the PE/G nanocomposites, the PE with the addition of GO exhibited superior toughness, while the stiffness of the PE was significantly enhanced by the G.
