Investigation of dielectric parameters of structural nanocomposites based on polyethylene

Abstract

The dependence of the dielectric constant and specific volume resistance of a structural composite based on (80 wt%) synthetic isoprene rubber and (20 wt%) low density polyethylene on the content of nanosized particles of aluminum fillers, Nalchikin and carbon black in small quantities is shown graphically. Using an electron probe method for studying the microstructure of a structural material, a hydrostatic weighing method based on determining the density of a composite by its double weighing and an electron shadow microscope, this paper presents models and physical mechanisms that lead to extrema in the permittivity and conductivity of composite materials.
