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

Saturation effect for dependence of the electrical conductivity of planar oriented nematic liquid crystal 6CB on the concentration of Cu7PS6 nanoparticles

“…As shown in [12], changing the liquid crystal (from 6СНВТ to 6CB) leads to a much greater influence of Cu 6 PS 5 I nanoparticles on the electrical conductivity. However, from coloring liquid crystal to green when the Cu 6 PS 5 I nanoparticles were introduced into the 6CB liquid crystal, it was concluded that in a more polar, than 6СНВТ, 6CB liquid crystal some of the Cu 6 PS 5 I molecules dissociate.…”

Influence of anion substitution on electrical conductivity of composites based on liquid crystal with Cu6PS5X (X = I, Br) nanoparticles

“…Cu 6 PS 5 I(Br) crystals belong to the compounds with argyrodite structure [1]. These materials are known as superionic conductors or solid electrolytes.…”

“…To significantly expand the limits of practical application of LC, it is necessary to be able to predictably change their properties. One of the methods for expanding the functional properties of LC is introduction of various types of nanoparticles [1][2][3][4]. As we have shown in Refs.…”

“…As we have shown in Refs. [1][2][3][4], significant changes in the properties of LC are observed when introducing superionic nanoparticles. The introduction of Cu 6 PS 5 I nano-particles into 6CB leads to an increase in conductivity by almost two orders of magnitude, which is caused by dissociation of nanoparticles in LC with formation of Cu ions [1].…”

“…[1][2][3][4], significant changes in the properties of LC are observed when introducing superionic nanoparticles. The introduction of Cu 6 PS 5 I nano-particles into 6CB leads to an increase in conductivity by almost two orders of magnitude, which is caused by dissociation of nanoparticles in LC with formation of Cu ions [1]. The purpose of this work was to investigate the influence of Cu 6 PS 5 Br superionic nanoparticles on the dielectric properties of a planar-oriented nematic 6CB and to compare it with the results of the influence of Cu 6 PS 5 I superionic nanoparticles on this LC.…”
