Some novel optical methods to study the structure of ordered latices have been developed. These methods, as well as the Bragg diffraction technique, have been used in rheo- and electro-optical studies of latex structure. In the rheo-optical studies, ordered latices were subjected to a simple shear field and a three-dimensional deformation of the structure was observed. The increase in spacing between parallel layers of particles is qualitatively explained by a proposed two-dimensional sliding layer model. In the electro-optical studies, ordered latices were subjected to an electric field and an asymmetrical particle distribution was found. The electric field effect was found to be large for low volume fractions and low ion concentrations. These dependencies are explained semi-quantitatively by a proposed model. / A widely used equation describing the optical condition of diffraction in ordered latices was reconsidered and given a firm theoretical basis.
