Maintaining comfort using photonic thermal management textiles has a large potential to decrease the energy cost for heating and cooling in residential and office buildings. We propose a thermoregulating fabric using metallic microparticles, which provides a dynamic and passive control of the infrared transmission, by adapting to the ambient temperature and humidity. The fabric is composed of tailored metal microparticles and a stimuli-responsive polymer actuator matrix, in order to benefit from strong scattering effects to control the wideband transmission of thermal radiation and to provide a sharp, dynamic response. The detailed numerical design demonstrates a wide dynamic ambient setpoint temperature window of ∼8 °C, with the wearer staying comfortable in the range between 18 and 26 °C. Its compatibility for large-scale manufacturing, with a safe and strong thermoregulating performance indicates a vital energy-saving potential and paves the way to a more sustainable society.
使用光子热管理纺织品来维持舒适度，在降低住宅和办公楼的供暖和制冷能源成本方面具有巨大潜力。我们提出了一种使用金属微粒的温度调节织物，它通过适应环境温度和湿度，对红外传输提供动态和被动控制。该织物由定制的金属微粒和刺激响应聚合物致动器矩阵组成，以便利用强散射效应来控制热辐射的宽带传输，并提供敏锐的动态响应。详细的数值设计表明，动态环境设定温度范围约为8°C，穿着者在18至26°C的范围内能保持舒适。其适用于大规模制造，具备安全且强大的温度调节性能，显示出巨大的节能潜力，并为迈向更可持续的社会铺平了道路。
