Advanced personal thermal management fabrics are being developed to realize improved human body thermal comfort and effectively regulate heat exchange between the human body and surroundings. Fiber-based thermal management fabrics are directly worn on soft and curved multiple curvature human body. Herein, a flexible photothermal fiber based on copper fractal dendrites with abundant CuO nanowires is designed. Well-aligned Cu fractal dendrite fiber is electrodeposited template freely via a low-cost and scalable process in an aqueous solution. Then, flexible CuO@Cu fractal dendritic photothermal fiber is fabricated by direct in situ oxidation and calcination of Cu fractal dendrites. Furthermore, the CuO@Cu fractal dendritic photothermal fiber can be woven into photothermal fabric by the traditional jacquard embroidery process. The temperature of photothermal fabric can be adjusted within the range of 35–65 °C by adjusting the number of photothermal fibers, which can be achieved with comfortable wearing of human thermal management and hot compress of hyperthermia to relieve local pain. Therefore, the Cu fractal dendrites have shown considerable potential for promoting the photothermal conversion of flexible personal thermal management.

基于原位生长 CuO@Cu 分形树突纤维的光热织物用于个人热管理

先进的个人热管理面料正在开发中，以实现改善人体热舒适性并有效调节人体与周围环境之间的热交换。基于纤维的热管理面料直接穿戴在柔软且弯曲的多曲率人体上。本文设计了一种基于具有丰富 CuO 纳米线的铜分形枝晶的柔性光热纤维。排列良好的铜分形枝晶纤维是通过低成本且可扩展的工艺在水溶液中自由电沉积模板。然后，通过Cu分形枝晶的直接原位氧化和煅烧制备了柔性CuO@Cu分形枝晶光热纤维。此外，CuO@Cu分形树枝状光热纤维可以通过传统的提花刺绣工艺编织成光热织物。通过调节光热纤维的数量，可以在35-65℃范围内调节光热织物的温度，实现人体热管理的舒适穿着和热敷热敷，缓解局部疼痛。因此，铜分形枝晶在促进灵活的个人热管理的光热转换方面显示出巨大的潜力。
