Influence of Cu₆PS₅І superionic nanoparticles on the dielectric properties of 6СВ liquid crystal

Abstract

Influence of Cu6PS5І nanoparticles on the dielectric properties of planarly oriented 6СВ liquid crystal (LC) is studied in the 10–106-Hz frequency range. Introduction of the nanoparticles is shown to result in an increase of the electric conductivity. Contrary to 6СНВТ LC, the conductivity monotonously depends on the nanoparticles’ concentration. The main reason of the much greater influence of Cu6PS5І nanoparticles on the 6СВ conductivity in comparison with 6СНВТ is related to a greater dissociation coefficient of Cu6PS5І in 6СВ than in 6СНВТ. This is confirmed by the fact that the dipole moment of the 6СВ molecules is greater than that of the 6СНВТ molecules.
