Abstract
The influence of Сu 7 GeS 5 I nanoparticles on the dielectric properties of planar- oriented liquid crystal 6CB has been investigated within the frequency range 6...10 6 Hz at the temperature 293 K. The concentration of nanoparticles varied within the range 0 to 0.1 wt.%. It has been shown that the Сu 7 GeS 5 I nanoparticles considerably less increase the conductivity of the liquid crystal (only by 1.3 times at their maximum concentration) than Сu 7 PS 6 ones, influence of which on the conductivity of the same liquid crystal we investigated earlier (24-fold increase in the conductivity at the same concentration of nanoparticles). It has been assumed that the main mechanism of conductivity changes when introducing Сu 7 GeS 5 I nanoparticles is the transfer of charge through nanoparticles. This mechanism of charge transfer is characterized by a rather strong dependence of the conductivity of the liquid crystal on the frequency and is experimentally observed especially at the maximum concentration of nanoparticles.
