Self-adaptive and large-area sprayable thermal management coatings for energy saving.

ABSTRACT: Self-adaptive thermal management over large areas is highly attractive since single-mode radiative cooling materials lead to undesired overcooling. However, it remains a challenge that dual-mode switchable materials require artificial stimuli or additional energy for switching between heating and cooling modes. Here, different from dual-mode switching materials driven by artificial stimuli or additional energy, we propose an autonomously self-adaptive dual-modal coating with assembled micro-heterostructures that can engender the multistage scattering of incident light. The resultant coating demonstrates 92% solar reflectivity and 93% emissivity in hot condition. More significantly, the coating reaches 60% visible light optical modulation, which is attributed to the formation and disruption
