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. 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.

The present invention is a process for performing rigid-to-rigid substrate lamination implementing pressure-sensitive adhesive (PSA). The process may include pressurizing a first sealed cavity to a first pressure. The process may further include creating a vacuum within a second sealed cavity, the second sealed cavity being sealed from the first sealed cavity by a flexible membrane. The process may further include applying the first pressure to a laminate assembly stack via the flexible membrane, the laminate assembly stack including a first substrate, a second substrate, and a PSA layer, the PSA layer being positioned between the first substrate and the second substrate. The process may further include applying the vacuum created within the second sealed cavity to the laminate assembly stack. The applied first pressure and the applied vacuum promote intimate contact between the first substrate and the second substrate of the laminate assembly stack via the PSA layer.

The present invention provides multiple layer glazing bilayers that utilize a masking layer over the polymer film component. The masking layer is specifically formulated to have a melting point that is less than the temperature employed in the autoclave process that is used to laminate the bilayer. The surprising result of the use of the specified masking layer of the present invention is a bilayer that can be processed according to conventional lamination methods but with a reduction in the damage and optical defects that normally occur during processing and installation of the bilayer product. After installation, the masking layer can be removed, exposing the previously protected, underlying polymer film.

Methods and devices are provided for improved large-scale solar installations. In one embodiment, a photovoltaic module is provided comprising a module front layer comprising a glass plate, a module back layer comprising an electrically conductive foil, and a plurality of solar cells arranged to be protected by the front layer and the back layer. In some embodiments, the module back layer is aluminum foil. The module back layer may have an externally exposed surface. The module back layer may be electrically grounded. An electrically insulating pottant material may be used with the solar cells to separate them from the module back layer. This allows for a high voltage withstand between the cells and the outer surface of the back layer.

摘要:
A thermal control film for use in spacecraft having a multi-layer interference filter adapted to exhibit high reflectivity to solar radiation, low absorptivity across the microwave spectrum and high emissivity in the far infra-red. The film is free from metal and extends over the active face of an antenna carried by the spacecraft. Such a film exhibits the desired thermo-optical properties for a thermal control radiator surface and can be used over the active face of a communications or radar antenna without disrupting the RF signal.
