Whereas cotton as an abundant natural cellulose has been widely used for sustainable and skin-friendly textiles and clothes, developing cotton fabrics with smart functions that could respond to various stimuli is still eagerly desired while remaining a great challenge. Herein, smart multiresponsive cotton fabric with hierarchically copper nanowire interwoven MXene conductive networks that are seamlessly assembled along a 3D woven fabric template for efficient personal healthcare and thermal comfort regulation is successfully developed. The robust hierarchically interwoven conductive network was "glued" and protected by organic conductive polymer poly(3,4-ethylenedioxythiophene) along a 3D interconnected fabric template to enhance interfacial adherent and environmental stability. Benefiting from the robust multiresponsive hierarchically interwoven conductive network, smart cotton fabric exhibits real-time response to various external stimuli (light/electrical/heat/temperature/stress), and the details of human activities can be accurately recognized and monitored. Furthermore, the porous structure of 3D smart fabric induced strong capillary force and confinement to phase change materials PEG, which exhibits a wide range of phase transition temperatures for efficient thermal comfort regulation. After further encapsulation with transparent fluorosilicone resin, the smart cotton fabric exhibits excellent self-cleaning performance with water/oil repellent. The smart multiresponsive cotton fabrics hold great promise in next-generation wearable systems for efficient personal healthcare and thermal management.
虽然棉花作为一种丰富的天然纤维素，已被广泛用于可持续和皮肤友好型纺织品和服装，但开发具有智能功能的棉花织物，使其能够对各种刺激做出响应，仍然是人们热切期望的，同时也是一个巨大的挑战。在此，我们成功地开发了一种具有多层次铜纳米线交织的 MXene 导电网络的智能多功能响应棉织物，这些导电网络沿着 3D 编织织物模板无缝组装，用于高效的个人保健和热舒适调节。坚固的多层次交织导电网络通过有机导电聚合物聚（3,4-亚乙基二氧噻吩）“胶合”并保护，沿着 3D 相互连接的织物模板增强了界面附着力和环境稳定性。得益于坚固的多功能多层次交织导电网络，智能棉织物能够实时响应各种外部刺激（光/电/热/温度/压力），并且可以准确识别和监测人体活动的细节。此外，3D 智能织物的多孔结构诱导了相变材料 PEG 的强毛细力和限制作用，从而表现出宽的相变温度范围，实现高效的热舒适调节。经过透明氟硅树脂的进一步封装，智能棉织物具有出色的自清洁性能，具有防水/防油功能。智能多功能响应棉织物有望在下一代用于高效个人保健和热管理的可穿戴系统中得到应用。
