Abstract
Thermoregulated multilayer material characterized in that it comprises at least one substrate and one thermoregulated layer, said thermoregulated multilayer material having: for λ radiation of between 0.25 and 2 μm, an absorption coefficient αm≥0.8; and, for incident λ radiation of between 7.5 and 10 μm, a reflection coefficient ρm: ρm≥0.85, when the temperature T of said multilayer material 1 is ≤100° C.; ρm between 0.3 and 0.85, when the temperature T of said multilayer material is between 0 and 400° C.
