In the context of low-carbon and energy conservation initiatives, smart thermal management textiles for the human body, which operate without energy consumption and pollution, are gaining increased attention. However, ensuring the fire safety of these textiles for human protection remains a key challenge for their practical application. Meanwhile, complicated and changed environments demand a high self-adaptation for designed textiles. This study introduces a dual-mode textile designed for freely switching radiative cooling (RC) and solar heating (SH). The textile is created by applying a high-white flame retardant and black phosphorus to both sides using a convenient scrape coating method. The combination of the cooling layer (90.0% solar reflectance and 95.9% infrared emissivity) and the heating layer (80% solar absorptivity) provides a comfortable thermal environment for the human body. Furthermore, a Janus coating, consisting of advanced flame retardants, synergistically enhances the textile's fire safety, confirmed by a limiting oxygen index of 28.0%, a reduction of 40.1% in the peak value of heat release, and self-extinguishing properties. This research presents a simple and convenient approach for creating dual-mode smart textiles for maintaining a comfortable micro-environment towards changing seasons and weather, significantly contributing to the development of fire-safe personal thermal management technology.

用于聚酯织物热管理和协同阻燃的先进 Janus 涂层


在低碳节能的背景下，无能耗、无污染的人体智能热管理纺织品越来越受到关注。然而，确保这些纺织品的防火安全以保护人体仍然是其实际应用的关键挑战。同时，复杂多变的环境要求纺织品设计具有高度的适应性。本研究介绍了一种双模式纺织品，设计用于自由切换辐射冷却（RC）和太阳能加热（SH）。该纺织品是通过方便的刮涂方法在两面涂上高白阻燃剂和黑磷而制成的。冷却层（90.0%太阳反射率和95.9%红外发射率）与加热层（80%太阳吸收率）的结合为人体提供了舒适的热环境。此外，由先进阻燃剂组成的Janus涂层可协同增强纺织品的防火安全性，其极限氧指数为28.0%，放热峰值降低40.1%，并具有自熄性能。这项研究提出了一种简单方便的方法来创建双模式智能纺织品，以在季节和天气变化时保持舒适的微环境，为防火个人热管理技术的发展做出重大贡献。
