Electronic textiles (e-textiles) hold great promise for serving as next-generation wearable electronics owing to their inherent flexible, air-permeable, and lightweight characteristics. However, these e-textiles are of limited performance mainly because of lacking powerful materials combination. Herein, a versatile e-textile through a simple, high-efficiency mixed-dimensional assembly of 2D MXene nanosheets and 1D silver nanowires (AgNWs) are presented. The effective complementary actions of MXene and AgNWs endow the e-textiles with superior integrated performances including self-powered pressure sensing, ultrafast joule heating, and highly efficient electromagnetic interference (EMI) shielding. The textile-based self-powered smart sensor systems obtained through the screen-printed assembly of MXene-based supercapacitor and pressure sensor are flexible and lightweight, showing ultrahigh specific capacitance (2390 mF cm ), robust areal energy density (119.5 µWh cm ), excellent sensitivity (474.8 kPa ), and low detection limit (1 Pa). Furthermore, the interconnected conductive MXene/AgNWs network enables the e-textile with ultrafast temperature response (10.4 °C s ) and outstanding EMI shielding effectiveness of ≈66.4 dB. Therefore, the proposed mixed-dimensional assembly design creates a multifunctional e-textile that offers a practical paradigm for next-generation smart flexible electronics.
电子纺织品（e-textiles）因其具有固有柔性、透气和轻质的特点，有望成为下一代可穿戴电子产品。然而，由于缺乏强大的材料组合，这些 e-textiles 的性能受到限制。在此，通过 2D MXene 纳米片和 1D 银纳米线（AgNWs）的简单、高效的混合维度组装，提出了一种通用的 e-textile。MXene 和 AgNWs 的有效互补作用赋予了 e-textiles 卓越的综合性能，包括自供电压力感应、超快焦耳加热和高效电磁干扰（EMI）屏蔽。通过 MXene 基超级电容器和压力传感器的丝网印刷组装获得的基于纺织品的自供电智能传感器系统具有柔韧性和轻质性，表现出超高比电容（2390 mF cm ）、稳健的面能量密度（119.5 µWh cm ）、出色的灵敏度（474.8 kPa ）和低检测限（1 Pa）。此外，相互连接的导电 MXene/AgNWs 网络使 e-textile 具有超快的温度响应（10.4°C s）和出色的 EMI 屏蔽效能≈66.4 dB。因此，所提出的混合维度组装设计创造了一种多功能的 e-textile，为下一代智能柔性电子产品提供了实用范例。
