Experimental study of the temperature dependence of the permittivity of nanocomposite materials based on a low-density polyethylene matrix with iron nanoparticles

Abstract

The temperature dependence of the dielectric permittivity of nanocomposites based on a high-pressure (low-density) polyethylene matrix with various concentrations of dispersed iron nanoparticles (2–22 wt %) has been studied. As the temperature increases from 0 to 40°C, the permittivity decreases for all concentrations of nanoparticles in the range studied. The results can be useful for developing thermostable acoustic waveguides.
