Thin layer lightweight and ultrawhite hexagonal boron nitride nanoporous paints for daytime radiative cooling

Published in Cell Reports Physical Science, 2022

  • Ultrawhite cooling paint is created incorporating hBN nanoplatelets and nanopores

  • High solar reflectance of 97.9% is achieved with 150-μm thin and lightweight layer

  • Full daytime cooling under direct sunlight with 5°–6°C below ambient on average

  • Simulations reveal high scattering coefficient and strong backscattering
