Abstract
Thermal radiation is the most ubiquitous form of heat. Developing new science and technology to dynamically control radiative heat transfer can bring a profound impact on the mitigation of global warming, in which thermal engineering becomes increasingly important. In this talk, I will introduce our recent electrochemically-driven device that can vary the thermal emissivity between 0.07 and 0.92, which serves as a powerful radiative thermal switch to control the heat transfer. The device is water-based, flexible, and non-volatile, which can be used as scalable building envelope thermoregulation to reduce the energy consumption and carbon footprint of space heating and cooling.
