Abstract

The collective dielectric relaxation studies have been carried out on nanoparticles/isotropic fluid mixed ferroelectric liquid crystals (FLCs). It has been observed from the dielectric loss spectra that the mixing of nanoparticles (Graphene Oxide and ZnO) and isotropic fluid (Water) into FLCs possesses two dielectric relaxations in low frequency range (i.e. Goldstone and associated novel relaxation). The behavior of novel relaxation peak is found to be anomalous in terms of its strong dependence on type of nanoparticles/fluids, external electric field and temperature variation. The effective dipolar contribution of nanoparticles/fluids into FLC dipole moment could be the probable reason for such relaxation.
