Abstract

All-season thermal management with zero energy consumption and emissions is more crucial to global decarbonization over traditional energy-intensive cooling/heating systems. However, the static single thermal management for cooling or heating fails to self-regulate the temperature in dynamic seasonal temperature condition. Herein, inspired by the dual-temperature regulation function of the fur color changes on the backs and abdomens of penguins, a smart thermal management composite hydrogel (PNA@H-PM Gel) system was subtly created though an “on-demand” dual-layer structure design strategy. The PNA@H-PM Gel system features synchronous solar and thermal radiation modulation as well as tunable phase transition temperatures to meet the variable seasonal thermal requirements and energy-saving demands via self-adaptive radiative cooling and solar heating regulation. Furthermore, this system demonstrates superb modulations of both the solar reflectance (ΔR = 0.74) and thermal emissivity (ΔE = 0.52) in response to ambient temperature changes, highlighting efficient temperature regulation with average radiative cooling and solar heating effects of 9.6 °C in summer and 6.1 °C in winter, respectively. Moreover, compared to standard building baselines, the PNA@H-PM Gel presents a more substantial energy-saving cooling/heating potentials for energy-efficient buildings across various regions and climates. This novel solution, inspired by penguins in the real world, will offer a fresh approach for producing intelligent, energy-saving thermal management materials, and serve for temperature regulation under dynamic climate conditions and even throughout all seasons.

具有太阳能和热辐射同步调制功能的生物启发智能双层水凝胶系统,可实现节能型四季温度调节
与传统的高能耗制冷/制热系统相比,零能耗和零排放的四季热管理对全球去碳化更为重要。然而,静态的单一制冷或制热热管理无法在动态的季节性温度条件下实现温度的自我调节。在此,受企鹅背部和腹部毛色变化的双重温度调节功能启发,通过 "按需 "双层结构设计策略,巧妙地创建了一种智能热管理复合水凝胶(PNA@H-PM Gel)系统。PNA@H-PM 凝胶系统具有同步太阳辐射和热辐射调制以及可调相变温度的特点,可通过自适应辐射冷却和太阳加热调节来满足不同季节的热需求和节能要求。此外,该系统还能根据环境温度的变化对太阳反射率(ΔR = 0.74)和热辐射率(ΔE = 0.52)进行出色的调节,从而实现高效的温度调节,其夏季平均辐射制冷和冬季平均辐射供暖效果分别为 9.6 °C和 6.1 °C。此外,与标准建筑基线相比,PNA@H-PM 凝胶为不同地区和气候条件下的节能建筑提供了更大的节能制冷/制热潜力。这种从现实世界中的企鹅获得灵感的新型解决方案将为生产智能节能热管理材料提供一种全新的方法,并可用于动态气候条件下的温度调节,甚至四季皆宜。
