Abstract:MXenes have emerged as promising candidates for enhancing the properties of self-healable flexible strain sensors by serving as conductive fillers. Leveraging the rich functional surface of MXene nanosheets, this study focuses on the transformation of F-rich MXene to O-rich MXene and explores its impact on the mechanical and healing properties of partially crystallized polymeric hydrogels. Through a facile hot-alkali process with KOH, the F terminations are replaced by O and OH groups, dominated by the earlier… Show more
