“…69,123 Contrary to this, there are reports suggesting that the removal of the terminal groups can enhance the stability of MXenes. 124 The surface groups can be removed by annealing in the presence of ammonia leading to nitridation of MXenes. It was also suggested that annealing under ammonia is 13 times more effective than annealing in an Ar environment.…”

Nanohybrid assemblies provide an effective platform for integrating the intrinsic properties of individual components into microscale fibers. In this study, a novel approach for creating mechanically and environmentally stable MXene fibers through the synergistic assembly of MXene and polyacrylonitrile (PAN), is introduced. Unlike fibers generated via a conventional stabilization process, which relies on air‐based stabilization to transform the PAN molecules into ring structures fundamental to carbon fibers, the hybrid fibers are annealed in an Ar atmosphere. This unique approach suggests MXene can serve as an oxygen provider that is essential for stabilizing PAN. As a result, significantly improved interfiber compactness is achieved and the oxidation stability of MXene is enhanced under atmospheric conditions. The resulting fibers exhibit exceptional stability, even after extended exposure to high humidity and elevated temperatures. This highlights the suitability of the thermally annealed MXene‐PAN (T‐MX‐PAN) fibers as robust electric heating elements. Notably, these fibers consistently generate heat over 1800 bending cycles. When integrated into fabrics, they demonstrate the capability to generate sufficient heat for melting ice and rapid evaporation. This study highlights the potential of T‐MX‐PAN fibers as next‐generation wearable heaters and offers valuable insights into advancing wearable technology in demanding environments.
