Abstract

In this paper, the electric properties of polar nanoparticles are examined. Special attention is paid to the terminology, classification and the physical bases of the different electric moments. A short history of the electro-optic studies of dipole moments of nanoparticles and the electro-optic Conferences is presented. The connection of the polar properties with the particle electric charge is considered. The potential of the colloid electro-optics for studying the properties of anisometric, anisotropic polar nanoparticles is discussed in details. Examples of such studies are presented. A comparative analysis is made of the potential of dielectric, electro-optic and dielectrophoretic measurements for studying the electric properties, size, shape and structure of polar nanoparticles.
