    Abstract: A hybrid solar window comprises: at least one glazing; a wave-length-selective solar mirror positioned to reflect IR toward an IR absorbing element. The IR absorbing elements comprises a conduit having a respective fluid inlet and fluid outlet, and an IR absorbing compound, wherein the IR absorbing compound is in thermal communication with the conduit. The wavelength-selective solar mirror has an average visible light transmittance of at least 50 percent and an average IR reflectance of at least 50 percent over the wavelength range of 850 to 1150 nanometers, inclusive. The IR absorbing element is configured to transfer thermal energy to a heat transfer fluid circulating through the conduit, wherein the IR absorbing element has an average visible light transmittance of at least 30 percent, and wherein each IR absorbing element has an average IR absorptance of at least 50 percent over the wavelength range 850 to 1150 nanometers, inclusive. Certain IR absorbing elements are also disclosed.

    Abstract: Provided are surfacing films that have a surface layer having opposed first and second major surfaces, the first major surface comprising a fluoropolymer surface and the second major surface optionally comprising a nanostructured surface. A printed layer can be disposed on the second major surface and can be at least partially embedded in the nanostructured surface, if present. As a further option, the fluoropolymer surface can be microreplicated to provide a frictional surface and/or provide aerodynamic drag reduction on aircraft structures. Optionally, the delamination peel strength of the surface layer from the remaining layers can be greater than the tensile strength of the surface layer.
