一句话总结

论文提出了一种智能纺织品，将动态热变色层与静态光子晶体相结合，使太阳反射率从用于加热的约0.6切换到用于降温的约0.9，从而实现无能源、随季节自适应的舒适性，并具有鲜明色彩。

ABSTRACT

A longstanding challenge in personal thermal management has been transitioning from static, appearance-limited passive radiative cooling (PDRC) materials to systems that are both dynamically adaptive and visually versatile. The central hurdle remains the inherent compromise between color saturation and cooling power. Inspired by organisms such as butterflies, which decouple structural color from thermal function, we present a smart textile that seamlessly merges a dynamic thermochromic layer with static photonic crystals (PCs). This design enables the solar reflectance to be autonomously switched-from approximately 0.6 in the colored state for heating to about 0.9 in the high-reflectance state for cooling. Consequently, outdoor experiments validated substantial temperature regulation: the fabric achieves a surface temperature reduction of 3-4 °C in summer and a heating difference of <1 °C in winter compared to commercial reference materials, all while maintaining high-saturation colors. This dual-mode operation offers a viable pathway for achieving adaptive, aesthetic, and energy-free thermal comfort.
