Abstract: The present disclosure provides methods, articles, and apparatuses related to altering electromagnetic radiation. A method of making articles includes a) forming an electromagnetic radiation altering material by providing a polymer matrix and optionally embedding dielectric particles in the polymer matrix and b) obtaining initial dielectric properties of the electromagnetic radiation altering material. The method further includes c) modeling electromagnetic radiation altering features of the material suitable for the article obtained from the material to have target electromagnetic radiation altering properties, thereby obtaining a simulation of the electromagnetic radiation altering article; and d) additive manufacturing the electromagnetic radiation altering article based on the simulation of the electromagnetic radiation altering article. An electromagnetic radiation altering article obtained by the method is also provided. Further, an apparatus is provided including the electromagnetic radiation altering article. Methods of altering electromagnetic radiation are provided, including integrating an electromagnetic radiation altering article into either an electronic device or an electromagnetic radiation producing device, or placing the article in the vicinity of the device. Aspects of the present disclosure advantageously contribute to achieving optimized materials and designs for electromagnetic radiation altering articles.

Abstract: The present disclosure provides compositions, articles, and methods related to altering electromagnetic radiation. An actinic radiation curable precursor composition of a three-dimensional article includes a) a resin comprising an actinic radiation curable component, wherein the resin has a viscosity no greater than 500 cP; b) hollow glass microspheres having a density no greater than 2 g/mL and an average diameter no greater than 200 micrometers; and c) a photoinitiator. At least part of the surface of the hollow glass microspheres comprises a surface coating or modification. An article includes a photo(co)polymerization reaction product of the composition. A method of manufacturing a three-dimensional article includes the steps of a) providing an actinic radiation curable precursor composition; and b) selectively exposing a portion of the composition to a source of actinic radiation to at least partially cure the exposed portion of the composition, thereby forming a cured layer. Steps a) and b) are repeated so as to form a three-dimensional article. A three-dimensional article is provided, obtained according to the method. Methods of interfering with electromagnetic radiation originating from an electromagnetic radiation producing device are provided, including integrating an article into the electronic device or placing an article in the vicinity of the electromagnetic radiation producing device.

Abstract: A thermal insulation/protection barrier that provides thermal insulation and protection to battery cells of a battery assembly. The barrier includes a cured silicone rubber foam layer comprising a plurality of firming particles disposed within the silicone rubber foam layer in an amount sufficient to impart additional firmness to the silicone rubber foam layer so that it takes a greater compressive force to compress the foam layer to a desired compression value, compared to the same silicone rubber foam layer without the firming particles.
