Coating to cool a surface by passive radiative cooling

Patent ·
OSTI ID:1637858
; ; ; ; ;
Disclosed herein in is a radiative cooling formulation comprising a first component with >55% reflectance in a wavelengths range of 0.3 to 2.5 microns, a second component with >0.85 peak thermal emissivity in a window range of 4 to 35 microns, and a third component to mechanically bind together a mixture of the first and second components.
