Abstract
The (polymer/liquid crystal) composite films were prepared from a solution of poly(dipropylfumarate) (Pdi-iPF) and nematic liquid crystal (LC) by a solvent casting method. The phase separated structure of the composite film was controlled by solvent evaporation rate. The light scattering (LS) profile of a (Pdi-iPF/LC:40/60 w/w) solution during solvent evaporation, exhibited a periodic structure, indicating that the phase separated structure was formed by spinodal decomposition. The aggregation structure of the composite film was investigated on the basis of a scanning electron microscope (SEM). SEM observation of the composite film suggested the presence of periodicity and dual connectivity of polymer and LC phases. The faster the solvent was evaporated, the smaller the LC channel (domain) size in the composite film was. The electro-optical behavior of the composite film was strongly depended on the LC channel (domain) size in the composite film. The transmittance increased, and also the rise and decay response times ((tau) <SUB>R</SUB> and (tau) <SUB>D</SUB>), decreased and increased, respectively, with an increase in size of LC channel (domain).
