Conductive textiles are promising components for next-generation wearable electronics. However, it is still a challenge for current conductive textiles and wearable electronic devices to survive in harsh environments, such as extreme mechanical damages and low/high-temperature stresses. Herein, we report ultrastrong, flame-retardant, intrinsically weldable, and highly conductive metallized Kevlar fabrics (MKFs) fabricated via polymer-assisted electroless deposition (ELD) and electrodeposition (ED) techniques. The combination of ELD and ED techniques effectively metallizes the Kevlar fabrics, enabling ultrahigh conductivity (sheet resistance <0.007 Ω sq−1). More importantly, the deposited metal layers significantly enhance the anti-impact properties of Kevlar fabrics by 2–3 times. Due to the inherent properties of Kevlar and effective metal coatings, the MKFs maintain conductivity while suffering various mechanical damages (GPa-scale tensile strength, cutting, sticking, etc.), high temperatures (∼300 °C), and even flame stresses. Surprisingly, the MKFs show intrinsic weldability with traditional solder materials. The multifunctional applications of such high-performance metallized fabrics are demonstrated as textile-based conductors, heaters, and supercapacitors, all of which could survive in extremely harsh conditions.

超强、阻燃、本征可焊接和高导电性金属化凯夫拉织物
导电纺织品是下一代可穿戴电子产品的有前途的组件。然而，目前的导电纺织品和可穿戴电子设备在极端机械损伤和低温/高温应力等恶劣环境中的生存仍然是一个挑战。在此，我们报告了通过聚合物辅助化学沉积 (ELD) 和电沉积 (ED) 技术制造的超强、阻燃、本征可焊接和高导电性金属化凯夫拉尔织物 (MKF) 。ELD 和 ED 技术的结合有效地将 Kevlar 织物金属化，实现了超高导电性（薄层电阻 <0.007 Ω sq -1）。更重要的是，沉积的金属层将 Kevlar 织物的抗冲击性能显着提高了 2-3 倍。由于 Kevlar 和有效金属涂层的固有特性，MKF 在承受各种机械损伤（GPa 级拉伸强度、切割、粘附等）、高温（~300°C）甚至火焰应力的同时保持导电性。令人惊讶的是，MKF 显示出与传统焊料材料的内在可焊性。这种高性能金属化织物的多功能应用被证明为基于织物的导体、加热器和超级电容器，所有这些都可以在极其恶劣的条件下生存。
