  • Metallo organo liquid crystals in a polymer matrix
    Patent number: 5843333
    Abstract: Polymeric dispersed liquid crystal composites containing a polymeric continuous phase and a discontinuous phase comprising a metallo organic mesogen. Also included are electro-optical films of such compositions and electro-optical devices containing such compositions. The continuous phase is a thermosetting or thermoplastic polymeric composition. The discontinuous phase may also contain non-metal containing liquid crystals that are compatible with the metallo organic mesogen.
