The (polymer/liquid crystal : LC) composite films consist of a continuous LC embedded in a three dimensional network of a polymer matrix. Since a polysiloxane chain composed of a flexible main chain, it is considered that the (polysiloxane network/LC) composite film can be easily stretched by an external deformation in order to change the orientation of the LC directors. In this study, poly(dimethylsiloxane-co-diphenylsiloxane)[P(DMS/DPS)] was used as a polymer matrix. P(DMS/DPS) was prepared by photopolymerization of vinyl terminated (dimethylsiloxane-co-diphenylsiloxane) macromonomer. The gel-like [P(DMS/DPS)/LC] composite film was obtained by swelling the P(DMS/DPS) with LC. The Electro-optic and mechano-optic properties were investigated for the [(P(DMS/DPS)/LC] composite film. The [(P(DMS/DPS)/LC] composite film showed low contrast even upon a high driving voltage also it was found for the mechano-optic measurement that the LC directors in the composite film were easily aligned along the external deformation direction.
