A composite cooling film including non-fluorinated organic polymeric layer, a metal layer disposed inwardly of the non-fluorinated organic polymeric layer, and an antisoiling, ultraviolet-absorbing hardcoat layer that is disposed outwardly of the non-fluorinated organic polymeric layer.

Composite cooling film comprising an organic polymeric layer, a UV-absorbing layer, and a reflective metal layer

A patterned optical retarder including non-overlapping first () and second () regions with respective first and second major surfaces having different RMS surface roughnesses. For substantially normally incident light over a wavelength range from about 400 nm to about 1000 nm, the optical retarder has different retardances in the respective first and second regions.

Patterned optical retarders and methods for making thereof

Catalyst comprising a first layer having an outer layer with a layer comprising Pt directly thereon, wherein the first layer has an average thickness in a range from 0.04 to 30 nanometers, and wherein the layer. Catalysts described herein are useful, for example, in fuel cell membrane electrode assemblies.

Catalyst

A lightguide includes features for extracting light that would otherwise be confined and propagate within the lightguide primarily by total internal reflection. A first portion of light propagating within the lightguide and extracted exits the lightguide through a first area of the lightguide having an optical reflectance of at least 30% and an optical transmittance of at least 5% for normally incident light at a wavelength of the extracted light. A second portion of light propagating within the lightguide and extracted exits the lightguide through a different second area of the lightguide having an optical transmittance of at least 80% for normally incident light at the wavelength of the extracted light.

Optical structures with off-state appearance area

The present disclosure includes a stretchable reflective film comprising a transparent polymer layer; a continuous metal layer comprising at least one of tin or indium; a non-reactive adhesive layer; and a stretchable film layer. The stretchable reflective film has at least 30% specular reflectivity when stretched by 50% of the unstretched length according to Specular Reflectivity Test Method.

Conformable reflective film having specified reflectivity when stretched at room temperature
