Biologically inspired flexible photonic films for efficient passive radiative cooling
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Some biological creatures have astonishing photonic structures to exhibit a thermal regulation ability. Taking inspiration from the brilliantly golden longicorn beetles, we demonstrate a bioinspired design of flexible hybrid photonic films ...
