Polymer nanocomposites based on Cu(Cu2O)-LDPE with a volume fraction of 0.1-0.4 copper filler in the form of spherical nanoparticles with sizes from 10 to 25 nm were synthesized. The electrical conductivity of such composite nanomaterials was measured, which is 4.5-5 times higher than the electrical conductivity of a polyethylene matrix. To predict the electrical conductivity of such materials, an analysis of well-known mathematical models is carried out and models for predicting the electrical conductivity of such materials are selected that are adequate to the experimental data. Keywords: polymer nanocomposite, electrical conductivity, metal-dielectric composites, mathematical models, Cu(Cu2O) filled polymer, low density polyethylene.
