  • Publication number: 20220355577
    Abstract: A composite material for passive radiative cooling is provided. In some embodiments, the composite material includes a base layer, and at least one emissive layer located adjacent to a surface of the base layer. In some embodiments, the at least one emissive layer is affixed to the surface of the base layer via a binding agent. In some embodiments, the surface of the base layer comprises a reflective substrate comprising an adhesive layer. In some embodiments, the at least one emissive layer is affixed to the base layer via the adhesive layer of the base layer.
