    Abstract: The present disclosure provides a radiative cooling article including a white diffusely reflective microporous layer and a non-white color reflective mirror film having first and second optical layers. The white diffusely reflective microporous layer has a solar weighted reflectivity at normal incidence of electromagnetic radiation over a majority of wavelengths in a range of 350 nanometers (nm) to 2500 nm of 0.8 or greater, 0.85, 0.9, or 0.95 or greater. The non-white color reflective film is disposed adjacent to a major surface of the white diffusely reflective microporous layer and the non-white color reflective film reflects a wavelength bandwidth of at least 30 nm within a wavelength range of 350 nm to 700 nm. The non-white color reflective film can be tuned to reflect light of a specific color (e.g., blue light, green light, or red light). The radiative cooling article may be useful for applications including commercial graphics located outdoors (e.g., on vehicles or buildings). The present disclosure further provides a composite cooling article including the radiative cooling article attached to a vehicle or a trailer. Also, the present disclosure provides a multi-surface passive cooling article including first and second elements in which at least one of the elements includes the radiative cooling article.

    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 multilayer fluoropolymer film comprising, in order: a first layer comprising a first polymer, the first polymer comprising at least 35 mol percent tetrafluoroethylene comonomer, at least 15 mole percent vinylidene fluoride comonomer, and at least 5 mol percent hexafluoropropylene comonomer, based on the total mol percent of the first polymer; a second layer comprising a second polymer, the second polymer comprising at least 50 mol percent vinylidene fluoride comonomer, based on the total mol percent of the second polymer; and a third layer comprising a third polymer, the third polymer comprising at least 50 mol percent methylmethacrylate comonomer, based on the total mol percent of the third polymer. The multilayer fluoroplymer films are useful for example, in multi-layer film applications (e.g., traffic sign protection, commercial graphic protection, paint protection, windows, windshields, building exteriors, and photo voltaics).
