A COOLING MATERIAL

摘要

The present disclosure provides a cooling material which comprises a first spectrally selective component that comprises particles. The particles are arranged for emission of radiation predominantly having a wavelength or wavelength range within an atmospheric window wavelength range in which the atmosphere of the earth has a reduced average absorption and emission compared with an average absorption and emission in an adjacent wavelength range. Consequently, the cooling material is arranged for emission of thermal radiation and absorption of radiation from the atmosphere within that wavelength range is reduced. The cooling material further comprises a second spectrally selective component having a property that distinguishes the second spectrally selective component from the first spectrally selective component and facilitates at least one desired function of the cooling material.
