Abstract: Ultraviolet-C (UV-C) radiation shielding films including a substrate made of a fluoropolymer, a multilayer optical film disposed on a major surface of the substrate, and a heat-sealable encapsulant layer disposed on a major surface of the multilayer optical film opposite the substrate. The multilayer optical film is made of at least a multiplicity of alternating first and second optical layers collectively reflecting at an incident light angle of at least one of 0°, 30°, 45°, 60°, or 75°, at least 30 percent of incident ultraviolet light over at least a 30-nanometer wavelength reflection bandwidth in a wavelength range from at least 100 nanometers to 280 nanometers. The ultraviolet light shielding film may be applied to a major surface of a photovoltaic device, such as a component of a satellite or an unmanned aerial vehicle. Methods of making the UV-C radiation-protective films also are disclosed.

Abstract: Multilayer infrared (IR) reflecting films are provided. An optical repeating unit of the film include a plurality of optical polymeric layers arranged to reflect light by constructive and destructive interference. Optical layer A is a high refractive index polymeric layer, and optical layer B is a low refractive index isotropic polymeric layer containing fluoropolymers. The film has an average reflectance of about 50% to about 100% in a near infrared wavelength range of about 850 nm to about 1850 nm, and an average transmission of about 70% to about 90% in a visible light range.

Abstract: A light guide comprising a polymeric layer at least 25 percent transmissive over at least a 30 nm bandwidth in a wavelength range from 180 to 280 nm over a distance of at least 100 micrometers and visible light transparent reflecting layers (UV-C mirror) that are at least 50 percent reflective over at least 30 nm bandwidth in a wavelength range from 180 to 280 nm over an incident light angle of 0 to 90 degrees and that are at least 25 percent transmissive of visible light over at least 30 nm bandwidth in a wavelength range of 400 to 800 nm over an incident light angle of 0 to 90 degrees. The light guide is useful, for example, for antimicrobial surfaces.

Abstract: Surface structured articles comprising a polymer matrix and a dispersed phase, the article having first and second opposed major surfaces, at least a portion of the first major surface is a microstructured, anisotropic surface comprises features having at least one dimension in a range from 1 micrometer to 500 micrometers, wherein the dispersed phase comprises an antimicrobial material, and wherein at least a portion of the dispersed phase is present on the microstructured, anisotropic surface. Surface structured articles are useful, for example, for marine applications (e.g., surfaces in contact with water (e.g., fresh water, ocean water)) such as boats, ships, piers, oil rigs, decks, and roofing materials.

Abstract: A passive cooling article is disposed on a substrate to cool the substrate. The article includes an outer layer having a high absorbance in the atmospheric window region of the electromagnetic spectrum and having a high transmittance in the solar region of the spectrum. The article also includes a reflector having a high reflectivity in the solar region of the spectrum. At least one of the outer layer and the reflector includes a fluoropolymer. Micro-sized particles or surface structures may be disposed in or on the outer layer or the reflector to improve absorbance. A metallic layer may be disposed between the fluoropolymer and the substrate to be cooled.
