Abstract

The effect of nickel nanoparticles stabilized by a polyethylene matrix on the physical-mechanical and thermal properties of nanocomposites based on high-pressure polyethylene was studied by X-ray phase (XRD) and differential thermal (DTA) analyzes.An improvement in the strength and deformation parameters, as well as the thermal-oxidative stability of the obtained nanocomposites was revealed, which can be attributed to the effects of structural modification of the polymer matrix.Small amounts of nanofiller introduced into the polymer play the role of structure-forming agents - artificial nuclei of crystallization, which contributes to the formation of a small-spherolite structure in the polymer, characterized by improved physical, mechanical and thermal properties of the obtained nanocomposite.fi
