In recent years, Nanoparticles doped Ferroelectric composites become more attractive for researchers around the globe due to its larger utilty in electro-optic display devices.This book communicates our experimental findings on nanoparticles doped liquid crystal composites, which shows that ZnO nanoparticles have improved the dielectric permittivity of ferroelectric liquid crystals and hence contribute to molecular ordering of the smectic layers.
