Passive radiative cooling paint

WebPassive daytime radiative cooling (PDRC) is an electricity-free method for cooling terrestrial entities. In PDRC, a surface has a solar reflectance of nearly 1 to avoid solar heating and a high emittance close to 1 in the long-wavelength infrared (LWIR) transparent window of the atmosphere (wavelength λ = 8–13 μm) for radiating heat to the cold sky. This allows the … Web28 Oct 2024 · In this theoretical study, a disordered metamaterial coating with randomly embedded TiO 2 dielectric microspheres in a polydimethylsiloxane matrix has been designed for the purpose of daytime passive radiative cooling.
