Resumo

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.
