Abstract

Radiative cooling coating (RCC) provides a sustainable pathway for thermal management. However, the spectrally engineered RCC’s thermal regulation behavior relies heavily on clear weather, limiting the development of its adaptive thermal management performance and high cooling power. Inspired by the skin’s thermo-regulation, we report a bionic skin meta-gel coating (BSMC) with an adaptive spectrum and moisture modulation capability through hierarchical structure design and localized molecular confinement engineering. Autonomous thermal regulation and high cooling power are attained for the BSMC. Compared to conventional RCC, the BSMC achieves superior cooling performance (a reduction of 4°C) at high temperatures. Conversely, the BSMC can heat a space via photo-thermal effect at low temperatures. Moreover, the BSMC addresses heat accumulation in thermal camouflage nets. According to calculations, the BSMC improves cooling power by 233 W/m² and significantly decreases global CO₂ emissions by 1.9 billion tons/year. The BSMC solves the bottleneck of RCCs and promotes global low-carbon development.

辐射冷却涂层（RCC）为热管理提供了一种可持续的途径。然而，光谱工程 RCC 的热调节行为在很大程度上依赖于晴朗的天气，这限制了其自适应热管理性能和高冷却能力的发展。受皮肤热调节的启发，我们报告了一种仿生皮肤元凝胶涂层（BSMC），通过分层结构设计和局部分子约束工程，该涂层具有自适应光谱和湿度调节能力。BSMC 可实现自主热调节和高制冷功率。与传统的 RCC 相比，BSMC 可在高温下实现卓越的冷却性能（降低 4°C）。相反，BSMC 还能在低温下通过光热效应加热空间。此外，BSMC 还能解决热伪装网中的热量积聚问题。根据计算，BSMC 可将制冷功率提高 233 瓦/平方米，每年可显著减少全球二氧化碳排放量 19 亿吨。BSMC 解决了 RCC 的瓶颈问题，促进了全球低碳发展。
