Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of NAUN Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

Abstract: In this work, Cu/LLDPE composites are obtained and it is shown that the method of combining the formation of the composite and the nanodispersed phase in the viscous-flow state of the polymer makes it possible to achieve a uniform distribution of nanoparticles in the matrix. The dielectric properties of the composites have been investigated. A change in the mechanism of electrical conductivity was revealed when the concentration of the nanodispersed phase was varied. At low frequencies, nanocomposites of this type exhibit through conductivity. It was found that no pronounced relaxation peaks are observed in the studied polymer nanocomposites. However, at high concentrations of the added additive > 20%, two weakly pronounced peaks appear in the region of low and high temperatures, which, with increasing temperature, shift towards higher frequencies
