Abstract: The present disclosure generally relates to polymer-aerogel/fiber composite materials, polymer-aerogel/textile composite materials, and systems and methods for producing them. The gel material can comprise, in some embodiments, a network of polymer. The fiber and/or textile material can comprise at least one of any natural, synthetic, and/or mineral fiber. In some cases, certain combinations of materials, solvents, and/or processing steps may be synergistically employed so as to enable manufacture of materials suitable for use in apparel, soft goods, and other consumer applications which may benefit from the properties of a polymer-aerogel/fiber composite and/or the polymer-aerogel/textile composite.

Abstract: A composite foam is provided having silica aerogel particles dispersed in a closed cell polymeric foam. The silica aerogel particles are included in a volume fraction between 2 and 60%, and the composite foam has a thermal conductivity of 40 mW/m?K or less and a density of 60 kg/m3 or less. In another embodiment, a composite foam is provided having a perforated closed cell polymeric foam and 2-60% hydrophobic silica aerogel particles by volume with a particle size distribution of 1 to 50 ?m, where the composite foam has a thermal conductivity of 30 mW/m?K or less, a density of 20-45 kg/m3, and an air permeability of 20-40 cubic feet per minute.

Abstract: An apparel garment includes a polyimide aerogel or aerogel-infused insulator 12 directly bonded to at least a portion 10 of the garment. A method for bonding an aerogel to an insulator 12 for an apparel garment includes providing a polyimide aerogel component, which may be a powder or other form, and directly bonding the polyimide aerogel component to the apparel garment. The bonding may be through at least one of thermal, chemical (adhesive/solvent), hydrogen, and mechanical bonding.
