The (polymer/liquid crystal: LC) composite films consisting of continuous LC embedded in a three dimensional network of a polymer matrix were prepared by solvent-induced phase separation method. When the polymer was not compatible with LC even in its isotropic state, no hysteresis on the applied voltage-light transmittance relationship was detected for the electro-optical switching. Poly (alkyl tetracyclododecene) (PATCD) was used as a polymer matrix of the (polymer/LC) composite film. Since PATCD is incompatible with LC, no hysteresis is expected. The (PATCD/LC) composite film was sandwiched between ITO PET film in order to apply an electric field in the direction perpendicular to the film surface. Electro-optic propeties, especially switching hysteresis of the (PATCD/LC) composite film were measured based on light scattering. The (PATCD/LC) composite film exhibited less hysteresis compared to the (PMMA/LC) composite film which exhibited considerable phase-mixing at (PMMA/LC) interface.
