摘要

The integration of personal thermal management, perception, protection, and comfort is essential for the development for next-generation textiles capable of performing in complex environments. Janus-designed textiles represent a promising route to this integration, offering adaptive dual-functionality. However, most current designs are limited to single-purpose applications, restricting their effectiveness in truly multifunctional scenarios. Here, we present a multifaceted Janus (X-Janus) textile that overcomes these limitations by combining innovative microporous polytetrafluoroethylene fibers with multidimensional nano- to microscale fibrils and MXene-coated carbon fabric. The X-Janus textile delivers multiple energy-independent functionalities: a spectral Janus design that enables adaptive thermal management through switchable radiative cooling or warming; an electrical Janus design that provides self-powered sensing and energy harvesting; and a wetting Janus design that ensures wearing comfort with waterproofness. Besides, the textile provides comprehensive protection including chemical resistance, electromagnetic interference shielding (56 dB), ultraviolet protection (UPF > 1,500), and flame retardancy. By integrating these advanced features, the X-Janus textile inspires new strategy for self-sustainable textiles, offering scalable solutions for outdoor safety, industrial wearables, and intelligent clothing where multifunctionality and environmental resilience are critical.
