Outdoor heat stress can cause health hazards for workers and reduce labor productivity, thus leading to an annual burden of US $6.2 billion for the Australian workforce. Because the outdoor temperature fluctuates within a day, self‐regulating textiles are urgently needed to keep the temperature of the human body stable. Smart textiles are able to sense their surrounding environment and can respond by adapting their behaviors accordingly. However, there are a number of challenges in utilizing functional materials to achieve smart thermal radiation management for outdoor comfort and energy saving without using an external power supply. Here, a smart textile with thermal radiation management is designed by combining vanadium dioxide (VO₂) and silver (Ag) strips on polyester (PET). This well‐designed VO₂/Ag–PET exhibits high thermal management efficiency with a decrease of 13.9 °C at in‐box temperature under intense radiation while remaining transparent to thermal radiation at low temperature. Moreover, the VO₂/Ag–PET shows good thermoresponsive and anisotropic electrical conductivity. In addition, it maintains 95% of its performance after bending. The proposed VO₂/Ag–PET textile has the potential to be used for thermal management, for wearable and flexible communication devices, and for energy saving applications.

具有各向异性和热响应电导率的智能热管理纺织品

室外热应激可能对工人造成健康危害并降低劳动生产率，从而给澳大利亚劳动力造成每年62亿美元的负担。由于室外温度会在一天内波动，因此迫切需要使用自调节纺织品来保持人体温度稳定。智能纺织品能够感知周围的环境，并可以通过相应地调整其行为来做出响应。但是，在不使用外部电源的情况下，利用功能材料实现智能的热辐射管理以实现室外舒适性和节能存在许多挑战。在这里，通过将二氧化钒（VO ₂）和银（Ag）条结合在聚酯（PET）上，设计了一种具有热辐射管理功能的智能纺织品。这个精心设计的VO₂ / Ag–PET表现出高的热管理效率，在强辐射下的箱内温度下降低了13.9°C，而在低温下仍对热辐射透明。此外，VO ₂ / Ag-PET具有良好的热响应性和各向异性的导电性。此外，它在弯曲后仍保持其性能的95％。拟议中的VO ₂ / Ag-PET纺织品具有用于热管理，可穿戴和灵活通信设备以及节能应用的潜力。
