Abstract: A composite cooling film (100) comprises an ultraviolet-reflective multilayer optical film (120) and a reflective microporous layer (110) secured thereto. The ultraviolet-reflective multilayer optical film (120) hat is at least 50 percent reflective of ultraviolet radiation over a majority of the wavelength range of at least 340 but less than 400 nanometers. The reflective microporous layer (110) has a continuous phase comprising a nonfluorinated organic polymer and is diffusely reflective of solar radiation over a majority the wavelength range of 400 to 2500 nanometers, inclusive. The composite cooling film (100) has an average absorbance over the wavelength range 8-13 microns of at least 0.85. An article (1200) comprising the composite cooling film (100) adhered to a substrate (1210) is also disclosed.

Abstract: (Co)polymer matrix composites including a porous (co)polymeric network; a multiplicity of thermally-conductive particles, a multiplicity of intumescent particles and optionally a multiplicity of endothermic particles distributed within the (co)polymeric network structure; wherein the thermally-conductive particles, intumescent particles and optional endothermic particles are present in a range from 15 to 99 weight percent, based on the total weight of the particles and the (co)polymer (excluding the solvent). Optionally, the (co)polymer matrix composite volumetrically expands by at least 50% over its initial volume when exposed to at least one temperature greater than 135° C. when exposed to at least one temperature greater than 135° C. Methods of making and using the (co)polymer matrix composites are also disclosed. The (co)polymer matrix composites are useful, for example, as heat dissipating or heat absorbing articles, thermally-initiated fuses, and fire-stop devices.
