Electrophysical Properties of Nanocomposites on the Basis of Polychlorotrifluoroethylene and Magnesium Oxide Modified with Copper Iodide

Abstract

The electrophysical properties of magnesium oxide chemically modified with copper iodide have been studied in the superfrequency range and low-frequency in the temperature range 25 – 170^оС and a concentration of from 0 to 0.8 volume. It has been found the optimal volume content of copper iodide (~ 0.75) in the composites CuI/MgO, when the interfacial interaction shows most intensively and maximum values electrical parameters take place. It is shown that the polymer composites containing CuI/MgO have higher values of the real and image complex dielectric permittivity and conductivity as compared with a system which does not contain modified components.Keywords: interfacial interaction, conductivity, dielectric permittivity, nanocomposites, copper iodide.
