Abstract：Ti_3C_2Tx MXene, as a novel two-dimensional layered material, is considered a promising building block for fiber fabrication due to the outstanding mechanical, electrical, electrochemical, photothermal conversion, and biocompatibility properties. However, the mechanical, electrical, and electrochemical performances of MXene fibers are far lower than intrinsic properties of Ti_3C_2Tx nanosheets because of the self-stacking during the assembling process, interlayer structural defects, and weak interfacial interactions of Ti_3C_2Tx nanosheets. In view of the above-mentioned existing problems, this review elaborates on the spinning of MXene fibers and their microstructure design. Meanwhile, the strategies for improving the mechanical, electrical and electrochemical properties of MXene fibers are discussed, the existing challenges of MXene fibers are summarized, and the upcoming trends in MXene fibers are prospected. By further optimizing the design of electrode materials, preparation processes,and their functional integration, MXene fibers are expected to play an important role in next-generation highperformance wearable devices and advanced functional materials.
