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.

Abstract: A composite material for coating a textile substrate. The composite material includes a polymer matrix and a particulate addition, wherein the particulate addition is 1-100% silica aerogel particles and 0-99% microspheres, by volume of the particulate addition. A textile assembly is also provided in which a first textile has a composite coating thereon, wherein the composite coating is made from the composite material. A method of making a textile assembly is also provided. The composite material is formed and then coated onto a first textile. In an embodiment, the particulate addition is effective to decrease thermal conductivity of the textile assembly by at least 30% compared to the textile assembly coated only with the polymer matrix.
