Abstract: A structural interface having an adaptive liquid crystal material that is positioned to receive electromagnetic radiation and adapted to reflect a selective band of the received electromagnetic radiation so as to help with cooling of a structure in the summer and/or heating of the structure in the winter. The adaptive liquid crystal material is designed to change its selective reflection band when exposed to an activating temperature or an activating light or both. Depending on the interior and/or exterior conditions, the adaptive liquid crystal material has one or more selective reflection bands with a peak wavelength selected from the following: within a sunlight wavelength span, outside a thermal infrared wavelength span, outside the sunlight wavelength span, or within the thermal infrared wavelength span. The structural interface may be applied to an exterior or interior surface of a structural envelop or be integrated into a structural envelope material.

Abstract: An identification medium cannot be reused when an attempt has been made to remove it from an object by using solvent. A cholesteric liquid crystal layer subjected to a hologram processing is formed while contacting a COP (cycloolefin polymer) layer. When the identification medium is removed using a solvent from a state in which it was adhered to an object by an adhesive layer, the COP layer is melted by the solvent and is damaged. The COP layer is a layer which functions as a substrate of the identification medium, and the identification medium is damaged by contacting with the solvent, as described above, and it is difficult to reuse.

Abstract: In this disclosure, a blue colorant is added in the adhesion layer of a reflective polarizer to compensate the chromaticity difference caused by the reflective polarizer itself and large horizontal viewing angle. The chromaticity difference can be further reduced by adding beads in the adhesion layer and/or forming light-gathering microstructures on the outer surface of the quarter wave plate of the reflective polarizer.
