The dominant factors that control the aggregation structure and electrooptical properties of polymer/liquid crystal (LC) composite films prepared by a solvent cast method were studied. The phase-separation behavior of the composite films was studied by evaluating the development of optical heterogeneity in the casting solution during film formation and by observing the morphology of the polymer networks. The study showed that the phase-separated structure of the polymer and LC was formed through spinodal decomposition and the resultant size of the LC domain in the composite film was controlled by regulating the solvent evaporation rate. The electrooptical properties were strongly dependent on the size of the LC domain.
