Abstract: Electrooptical properties of thin films of nematic liquid crystal-cellulose diacetate (NLC-CD) composite with self-organized structure. The composite samples were prepared at different rates of solvent evaporation on substrates inclined at various angles. The best optical contrast is obtained in composite films formed on substrates inclined at 45$^\circ$. The dependence of the small-angle scattering of light on the control electric field strength in the NLC-CD composite differs from the analogous dependence known for the traditional polymer-dispersed liquid crystal composites. It is established that the classical theory of the small-angle scattering does not adequately describe structural characteristics of the NLC-CD composite with self-organized structure.
