Abstract

Using ZnO nanoparticles stabilized in different HPPE and MPE matrices as nanofillers, nanocomposites based on HPPE and LPPE binary mixture were prepared and their properties and structures were studied. Composite materials based on a mixture of high- and low-pressure polyethylenes, including additives of finely dispersed zinc oxide stabilized by a matrix of maleinized high-pressure polyethylene, were studied using differential thermal analysis (DTA) and scanning electron microscopy (SEM). An enhancement in strength, deformation parameters and thermal and oxidative stability of composites was revealed with the introduction of finely dispersed zinc oxide, which is apparently due to the formation of interfacial bonds between zinc-containing nanoparticles and components of the polymer composition. The results show that when a small amount of nanofiller is introduced into the polymer volume, it is located at the interface of the structural elements of HPPE and LPPE and plays a structure-forming role, which leads to the formation of a fine spherulitic structure in the composites. This leads to an improvement in the physical-mechanical, thermal and thermophysical properties of the resulting nanocomposite.
