Abstract
Radiative cooling has the potential to drastically improve a wide range of energy conversion and utilization processes on Earth. However, the lack of tunability may limit its application in practical scenarios such as buildings, vehicles, and textiles. In this paper, we propose a new, to the best of our knowledge, approach to achieve tunable radiative cooling through a stretchable multilayer filter. The cooling power can be continuously modulated by mechanical stretching, which only requires a small amount of energy. This filter can be combined with existing static radiative cooling systems to achieve efficient and continuous regulation of cooling power.
