Composites Based on Isotactic Polypropylene and High-Pressure Polyethylene with Zinc-Containing Nanofillers

The effect of nanofiller (NF) additives containing zinc oxide nanoparticles stabilized by a polymer matrix of high pressure polyethylene obtained by the mechanochemical method on the structure and properties of metal-containing nanocomposites based on isotactic polypropylene (PP) and high pressure polyethylene (PE) using differential thermal (DTA) and X-ray phase (XRD) analyses was studied. The improvement of strength, deformation, and rheological parameters, as well as thermal-oxidative stability of the obtained nanocomposites, was revealed, which, apparently, is associated with the synergistic effect of interfacial interaction of zinc-containing nanoparticles in the PE matrix with the components of the PP/PE polymer composition. It is shown that nanocomposites based on PP/PE/NF can be processed both by the pressing method and by the injection molding and extrusion methods, which expands the scope of its application.
