摘要

消防防护服是消防员最大限度减少皮肤烧伤、确保消防作业和救援任务安全的重要防护装备。最近，人们越来越关注的是开发可结合到消防服中的自供电火灾报警材料，以在消防服着火之前为消防员提供主动消防保护。然而，简单地设计和制造具有动态表面适应性和透气性的基于热电（TE）纺织品（TET）的火灾报警电子产品仍然是一个挑战。在这里，我们开发了一种交替同轴湿法纺丝策略，以n型Ti3C2Tx MXene和p型MXene/SWCNT-COOH为核心材料，以坚韧的芳纶纳米纤维为保护壳，连续生产交替的p/n型TE气凝胶纤维，同时确保了TE发电的灵活性和高效性。利用这种交替的p/n型TE纤维，通过将交替的p-n段TE纤维缝合到芳纶织物中，成功地制备了具有高机械稳定性和耐磨性的基于TET的自供电火灾报警传感器。结果表明，在300°C的温差下，包含50对p-n对的基于TET的火灾报警电子设备产生7.5 mV的开路电压，功率密度为119.79 nW cm-2。然后，基于TE电压和温度之间的线性关系，将输出电压信号计算为相应的消防服表面温度。进一步展示了火灾报警响应时间和阻燃性能。这种自供电的火灾报警电子设备是真正的纺织品，具有透气性和与身体运动的兼容性，证明了它们在消防服中的潜在应用。

Temperature-Arousing Self-Powered Fire Warning E-Textile Based on p–n Segment Coaxial Aerogel Fibers for Active Fire Protection in Firefighting Clothing

Highlights

The p–n segment thermoelectric aerogel fiber was fabricated through an alternating coaxial wet-spinning strategy.
Resultant alternating p–n segment thermoelectric fiber was electrically connected in series (two p–n pairs with a length of 3 cm) with an outstanding electrical conductivity of 23.76 S m⁻¹.
Thermoelectric textile-based self-powered fire warning electronics exhibited sensitivity (trigger time within 1.43 s) and repeatable temperature sensing performance for firefighting clothing.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
