Strong and Tough MXene-Induced Bacterial Cellulose Macrofibers for AIoT Textile Electronics

Abstract Textile electronics with extraordinary sensing capabilities holds significant potential in the Artificial Intelligence of Things (AIoT). However, little effort is paid to their mutual advantages of robust interfacial interactions, ultra-strong mechanical performance, and stability. Herein, we fabricate homogeneous and multifunctional core–shell macrofibers by integrating bridge-functionalized MXene/PEDOT:PSS conductive ink with aligned bacterial cellulose (BC). These resulting macrofibers feature mechanical properties (tensile strength of 433.2 MPa and the Young’s modulus of 25.9 GPa), exceptional electrical conductivity (10.05 S cm −1 ) and durable hydrophobicity. Such superior robustness allows for…
