多模态过冷纺织品,全场景被动湿热舒适
Multimodal Super-Cooling Textiles for All-Scenario Passive Hygrothermal Comfort
中文简介
辐射冷却纺织品在全球气温上升的情况下实现个人热舒适度,同时提高生产率和节约能源方面具有巨大的前景。然而,尽管进行了广泛的研究,但大多数最先进的辐射冷却纺织品仅具有辐射功能,无法在所有场景下实现高效冷却,特别是在高温和高湿度降低非辐射冷却能力的情况下。本研究提出了一种多模态过冷纺织品,通过三维覆层策略集成了辐射、导电和蒸发机制,在不影响辐射性能的情况下增强了各种场景下的冷却效果。该方法使所有一维单纤维的表面都与二维氮化硼纳米片紧密三维包覆,从而通过高反向散射效率实现超高太阳反射率(97.30%)、全向散热(面内和面外导热系数分别为 2.40 和 0.33 W m−1 K−1)和单向吸湿排汗性能(传输指数为 1547%), 3D 导热网络结构和 Janus 润湿结构。在多重冷却机制的支持下,MST 在室外阳光下比棉花的温度降低 20 °C。即使在炎热潮湿的环境中,它仍然比棉花具有 2 °C 的

Radiative cooling textiles hold great promise for achieving personal thermal comfort amidst the rising global temperatures while enhancing productivity and saving energy. However, despite extensive research, most state-of-the-art radiative cooling textiles possess solely radiative functions, failing to achieve highly efficient cooling across all scenarios, particularly as high temperatures and high
