  • Publication number: 20090161061
    Abstract: Provided are multilayer laminates having one or more layers comprising twisted nematic liquid crystals and one or more layers of a polymeric sheet. The twisted nematic liquid crystal layers reflect infrared radiation. Thus, the multilayer laminates are useful to reduce the transmission of infrared energy. For example, in some embodiments the multilayer laminates are useful as windows to reduce energy consumption necessary to cool the interior of a structure such as an automobile or building. Preferably, the multilayer laminates retain one or more of the beneficial properties of safety glass. The multilayer laminates may include additional layers such as infrared absorbing layers, half wave plates, and the like, to minimize the transmission of infrared energy. The multilayer laminates may also include further additional layers such as polymeric films, polymeric sheets, rigid sheets, and the like.

  • Publication number: 20070152188
    Abstract: Provided is a composition comprising a nonmicellar twisted nematic liquid crystal having cholesteric near infrared-reflecting properties and at least one near infrared absorptive material. This composition reduces the transmission of near infrared radiation. The composition can be used as a layer, optionally in conjunction with polymeric films, polymeric sheets, rigid sheets, and the like, to form multilayer laminates. In some embodiments these multilayer laminates are useful as solar control windows or window films to reduce energy consumption necessary to cool the interior of a structure such as an automobile or building.
