MXene-based fibers are expected to have the hopeful potential for manufacturing multifunctional fabrics with permeability, lightweight, remarkable electrical conductivity, and outstanding mechanical properties. However, weak interaction between limits performance of fabrics, researchers still seeking a suitable solution easily scalable production methods. Here green novel wet-assembly approach is proposed producing non-woven MXene fiber (MFFs) constructed by random-oriented well-connected interfused fibers. The as-prepared porous lightweight while exhibiting high conductivity (708 S cm−1). A maximum specific achieved relatively low density (0.24 g cm−3), even superior individual Moreover, MFFs exhibit electromagnetic interference (EMI) shielding effectiveness 75.0 dB at thickness 107 μm, exceptional Joule heating (up 370 °C voltage 3.5 V), excellent photothermal conversion abilities, showing their great as high-performance in EMI shielding, wearable intelligent garments, personal applications.
