Influence of single-walled carbon nanotubes on dielectric and conductivity properties of smectic A liquid crystal with negative dielectric anisotropy


It was experimentally obtained that the presence of single-walled carbon nanotubes with concentration of 0.5% in the smectic liquid crystal with negative dielectric anisotropy reduces the transition temperature from the smectic to isotropic state. Both the longitudinal and transverse components of dielectric permittivity and the dielectric anisotropy are shown to increase in the presence of nanotubes. At the same time, the resulting percolation effect contributes to the increase in conductivity.

Keywords: liquid crystal, single-walled carbon nanotubes, dielectric relaxation, electric conductivity, threshold voltage.
