Abstract

The article is aimed at developing innovations in the field of hybrid polymer nanomaterials and investigating their structural, thermodynamic, and physico-mechanical properties. Filling the ethylene-octene copolymer with Ni nanoparticles as well as basalt scales increases the elasticity of the composite by a 25% and also causes an increase in strength by a 15%. Obtained results open possibility to evaluate influence of chemical nature, sizes and content of different kinds of fillers for improvement thermostability and elasticity of the new hybrid polymer nanomaterials.

Keywords

hybrid polymer nanomaterials, basalt flakes, nanometals, extrusion, thermal stability, elasticity, strength
