MXene Fiber-based Wearable Textiles in Sensing and Energy Storage Applications

Currently, flexibly wearable electronics greatly facilitate our life that can collect non-electrical signals such as physiological signals or body motions and then translate them into electrical signals such as current, voltage or resistance. With the development of next-generation wearable devices, functional and intelligent textile with softness, wearability and durability has attracted widespread attention, especially for fiber-based materials that are easy to modify. MXene, as an emerging two-dimensional (2D) material with excellent electrical conductivity, biocompatibility and hydrophilicity, enables accurate sensing and energy storing of fiber-based textiles. In this review, we focus on MXene fiber-based textiles that applied in sensing and energy-storing fields. At first, we summarized the typical fiber-based functional textiles as a brief introduction. Next, to better understand the important role of MXene in fiber-based textiles, synthesis, structure and properties of MXene were reviewed. Moreover, the fabrication methods for MXene fiber-based textiles including electrospinning, wet-spinning, biscrolling, three-dimensional (3D) Printing and coating are the fundamental strategies. At last, the applications of MXene fiber-based textiles in energy storing, sensing and other fields were demonstrated, enabling more advanced and multifunctional textiles, and would be playing an important role in future wearable electronics.
