Electronic textiles are promising for wearable devices. However, wearable electronic textiles face with challenges such as weak interface binding force, difficulty in multifunctional coupling, insufficient fire safety, and the lack of fabric intrinsic properties. Herein, a flexible and wearable cotton fabric (C-P-M-Cotton) was fabricated via hydrogen bonding, electrostatic assembly, and covalent cross-linking, using TiCT MXene, phytic acid (PA), and an isocyanate-based cross-linking agent. The integration of fire safety, strain sensing, and thermal management functionalities was successfully achieved in cotton fabric. C-P-M-cotton was utilized as a sensor to detect and distinguish motion and information signals from the body and demonstrated a long-term stable conductivity and sensing performance, only a 10.5% decrease in conductivity, and a consistent resistance signal response curve during 6000 s after one year of storage in air. Additionally, the C-P-M-cotton exhibited thermal management properties in cold climates through a triple-mode heating, including electrothermal heating (100 °C at 10 V), solar heating (59.5 °C at 1000 W/m), and radiative heating (2.9 °C). Moreover, C-P-M-cotton self-extinguishes after the removal of the external ignition source with a limiting oxygen index (LOI) of 45.1%. This work offers an approach and valuable insights for the development of the next generation of durable wearable flame-retardant electronic textiles, highlighting their potential applications in motion monitoring and thermal management.
电子纺织品在可穿戴设备领域颇具前景。然而，可穿戴电子纺织品面临着诸如界面结合力弱、多功能耦合困难、消防安全不足以及缺乏织物固有特性等挑战。在此，通过氢键、静电组装和共价交联，利用TiCT MXene、植酸（PA）和异氰酸酯基交联剂制备了一种柔性可穿戴棉织物（C-P-M-Cotton）。在棉织物中成功实现了消防安全、应变传感和热管理功能的集成。C-P-M-棉被用作传感器来检测和区分来自身体的运动和信息信号，并展示出长期稳定的导电性和传感性能，在空气中储存一年后6000秒内电导率仅下降10.5%，且电阻信号响应曲线一致。此外，C-P-M-棉在寒冷气候下通过三种模式加热展现出热管理特性，包括电热加热（10V时100°C）、太阳能加热（1000W/m²时59.5°C）和辐射加热（2.9°C）。而且，C-P-M-棉在移除外部火源后能自熄，极限氧指数（LOI）为45.1%。这项工作为下一代耐用可穿戴阻燃电子纺织品的开发提供了一种方法和宝贵见解，突出了它们在运动监测和热管理方面的潜在应用。
