Abstract: The present disclosure relates to articles and methods of sealing light redirecting film constructions comprising a microstructured optical film, such as a daylight redirecting film, bonded to another film. This type of assembly may serve various purposes. For example, the assembly may protect the structured film, provide additional functionality, such as diffusion or infrared reflection, and/or facilitate attachment of the microstructured optical film to a mounting surface, such as a glazing or window pane. The methods for sealing the edge of a light redirecting construction inhibit ingress of water and other contaminants during the film installation and afterwards during its regular use.

Abstract: The present disclosure provides a thermally conductive article including a pad having first and second opposed major surfaces and a thickness therebetween. The thickness is formed of entangled thermally conductive fibers and at least a portion of the entangled thermally conductive fibers have at least one terminal end at the first opposed major surface, the opposed second major surface, or both. The pad is at least partially impregnated with a polymer. Another thermally conductive article is provided including a) a pad having first and second opposed major surfaces and a thickness therebetween; b) a first thermally conductive skin layer; and c) a second thermally conductive skin layer. The thickness of the pad is formed of aligned thermally conductive fibers, and at least a portion of the thermally conductive fibers have a terminal end at the first opposed major surface and the opposed second major surface. The first and second thermally conductive skin layers each include a polymeric matrix at least partially embedded in the terminal end of at least a portion of the thermally conductive fibers at the first and second major surfaces of the pad, respectively. Methods of making the thermally conductive articles are also provided.
