Light Extinction in a Dispersion of Small Nematic Droplets

Abstract

The light transmission properties of materials in which submicron size nematic droplets are dispersed in a solid polymeric matrix are studied. Theoretical calculations of the differential and total cross sections have been performed in the Rayleigh-Gans approximation for different nematic director configurations. The effect of interdroplet interference is discussed in relation to the droplet distribution, and different models for the pair correlation function are taken into account. An attenuation coefficient is defined and calculated for different director configurations. Theoretical calculations are in excellent agreement with experimental data obtained from thin films of materials consisting of droplets of cyanobiphenyls is dispersed in an epoxy resin.
