Modification in dielectric properties of SWCNT doped ferroelectric liquid crystals

Effect of single walled carbon nanotubes (SWCNT) in ferroelectric liquid crystal (FLC) geometry has been studied for low and high concentrations of dopant. The results are compared with the characteristics of pure FLC system. An appreciable change in dielectric permittivity, relaxation behavior and other vital parameters has been observed for SWCNT doped FLC system, which shows the adaptability of carbon nanotubes with that of pure FLC molecule. Under high electric field, highly concentrated SWCNT doped FLC shows enormously large values of dielectric loss. This is due to the high conductivity of SWCNT at higher electric field. Interestingly, such effect is not much prominent for the low concentration of the SWCNT doped FLC system. ► The carbon nano tubes (CNTs) can be used to alter the properties of Liquid crystals material. ► The ferroelectric liquid crystals (FLCs) have significant advantages in display applications. ► The utility of doping CNTs in FLC system change the dielectric parameters. ► The dispersion characteristics of CNT doped FLC system for low and high concentration of SWCNTs has been explored.
