Self-adaptive thermal management over large areas is highly attractive since

single-mode radiative cooling materials lead to undesired overcooling. How-

ever, it remains a challenge that dual-mode switchable materials require arti-

?cial stimuli or additional energy for switching between heating and cooling

modes. Here, different from dual-modeswitching materials driven by arti?cial

stimuli or additional energy, we proposean 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 re?ectivity and 93% emissivity in hot condition. More signi?cantly,

the coating reaches 60% visible light optical modulation, which is attributed to

the formation and disruption of the conjugation region in the chromogenic

molecules, to prevent overcooling in cold condition. A thermal-switchable

fabric is further fabricated via large-area spraying processes, demonstrating

2.5 °C warmer in cold condition and 8.7 °C cooler in hot condition compared to

white samples. The coating highlights the importance of the large-scale

manufacturing of temperature-adaptive materials, providing insights into the

application of dynamic radiative cooling in garment, camping, building and

other ?elds.
