Researchers report that a photonic film, composed of a micropyramid polymer matrix with ceramic particles and inspired by fluffs on the longicorn beetle that help the beetle regulate its temperature, can reflect 95% of incoming solar radiation and emit infrared energy to achieve up to 5.1° C of passive radiative cooling in direct sunlight.
