Scientific Achievement
Developed a printable thin film structure that automatically switches its sky-window emissivity in response to environment temperature, while delivering an albedo that is optimized for maximal year-round energy saving or indoor thermal comfort.
Significance and Impact
Achieved the first printable temperature-adaptive radiative cooling structure for large-scale application. The photonic mechanism employed in this material also opens a new path for scalable dynamic structures in the mid-IR spectrum.
Research Details
