Passive radiative cooling paint

WebOne alternative to energy-intensive cooling methods is passive daytime radiative cooling (PDRC)—a phenomenon where a surface spontaneously cools by reflecting sunlight [wavelengths (λ) ~0.3 to 2.5 μm] and radiating heat to the cold outer space through the atmosphere’s long-wave infrared (LWIR) transmission window (λ ~ 8 to 13 μm). WebPassive radiative cooling provides an energy-saving method for heat management in buildings. Solar reflective paints are versatile and scalable formats that can be readily applied for this cooling technology. We investigate solar reflective paints consisting of hollow silica (SiO 2 ) and hollow titanium dioxide (TiO 2 >) microparticles as pigments and …
