Abstract: A passive thermal management system and methods of using a thermoresponsive hydrogel coating configured to autonomously switch between a heating state and a cooling state based on ambient temperature. At temperature greater than a lower critical solution temperature of the thermoresponsive hydrogel, the thermoresponsive hydrogel coating becomes solar reflective and has enhanced radiative cooling ability to achieve daytime radiative cooling. At temperatures less than the lower critical solution temperature, the thermoresponsive hydrogel coating becomes transparent to facilitate absorption of solar radiation by sun absorber.
