Webinar - Ultra-White Paints for Full Daytime Sub-Ambient Radiative Cooling
Space cooling consumes significant amount of power, which is often generated through carbon-emitting processes. Moreover, the heat is rejected to the ambient on the earth, contributing to urban heat island effect and global warming. We have designed and fabricated ultrawhite BaSO4-acrylic and CaCO3-acrylic radiative cooling paints that reflect 98.1% and 95.5% of sunlight respectively (only absorb 1.9% and 4.5% respectively). Meanwhile, the painted surface strongly emits infrared... Details
