Effect of Nanomaterials on Physical Properties of Liquid Crystals

Abstract

Liquid crystals are the fourth state of matter whose order lies between that of 3-dimensionally ordered solids and completely disordered fluids. The physical parameters such as threshold voltage, dielectric anisotropy, and elastic constants are the key factors in designing liquid crystal display devices. In this chapter, we have reviewed the effect of nanomaterials viz. carbon nanotubes, quantum dots, and nanoparticles and their derivatives in liquid crystal-nanocomposites on the electro-optic switching, threshold voltage, dielectric anisotropy and elastic constants of the nanocomposites.
