摘要:
Provided are multilayer laminates having one or more layers comprising twisted nematic liquid crystals and one or more layers of a polymeric sheet comprising a polymer with a modulus between 20,000 psi (138 MPa) and 100,000 psi (690 MPa). 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 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.
摘要(中):
提供了具有一层或多层包含扭曲向列型液晶的多层层压体和一层或多层包含20,000psi(138MPa)和100,000psi(690MPa)之间的模量的聚合物的聚合物片。 扭转的向列液晶层反射红外辐射。 因此,多层层压板可用于减少红外能量的传输。 例如,在一些实施例中,多层层压板可用作窗口以减少冷却诸如汽车或建筑物的结构的内部所需的能量消耗。 优选地,多层层压体保持安全玻璃的有益特性。 多层层压体可以包括另外的层,例如红外线吸收层,半波片等,以最小化红外能量的传输。 多层层压体还可以包括另外的另外的层,例如聚合物膜,聚合物片,刚性片等。
