Abstract

In the frequency range of 6–10⁶ Hz at a temperature of 293 K, the influence of (Cu₆PS₅I)_0.5(Cu₇PS₆)_0.5 superionic nanoparticles on electrical conductivity and dielectric properties of 6CB liquid crystal are investigated. Parameters of near-electrode and bulk processes are evaluated as well as their changes at introducing nanoparticles into the LC are investigated. It is shown that the effect of nanoparticles of solid solution (Cu₆PS₅I)_0.5(Cu₇PS₆)_0.5 is smaller than the effect of Cu₆PS₅I nanoparticles. It is suggested that the surface properties of solid solution nanoparticles are mainly determined by Cu₇PS₆ component of a solid solution. Significantly less interaction of nanoparticles of solid solution (Cu₆PS₅I)_0.5(Cu₇PS₆)_0.5 with molecules of 6CB LC than the interaction of Cu₇PS₆ nanoparticles with molecules of liquid crystal is established.

摘要

在6-10 ⁶ Hz的频率范围内，在293 K的温度下，研究了(Cu ₆ PS ₅ I) _0.5 (Cu ₇ PS ₆ ) _0.5超离子纳米粒子对6CB液晶电导率和介电性能的影响。评估了近电极和本体过程的参数，并研究了它们在将纳米粒子引入 LC 时的变化。结果表明，固溶体(Cu ₆ PS ₅ I) _0.5 (Cu ₇ PS ₆ ) _0.5纳米颗粒的影响小于Cu ₆的影响PS ₅ I纳米颗粒。这表明固溶体纳米粒子的表面性质主要由固溶体的Cu ₇ PS ₆组分决定。固溶体(Cu ₆ PS ₅ I) _0.5 (Cu ₇ PS ₆ ) _0.5纳米粒子与6CB LC 分子的相互作用比Cu ₇ PS ₆纳米粒子与液晶分子的相互作用显着更小。
