Abstract
The pristine and dispersed NPs in NLC have been analyzed by means of optical texture, optical transmittance and dielectric spectroscopy. We observed that dispersion of TiO2 nanoparticles (NPs) in nematic liquid crystal (NLC) has suppressed the undesired ionic effect. The reduction of ionic effects has been attributed to the strong adsorption of ionic impurities on the surface of TiO2 nanoparticles. The optical transmittance curve reveals that relaxation processes are faster than the host materials, after the field is turned off. The faster relaxation in dispersed system is accredited to the decrease in the rotational viscosity and suppressed screening effect.
