Abstract
Ti3C2Tx MXene nanosheets hold significant promise to create electronic textiles (e-textiles) due to their excellent electrical conductivity, reactive surfaces, and facile solution processability. However, their poor oxidation stability and weak adhesion to textile fibers remain key challenges for achieving highly conductive and stable e-textiles. Additionally, the oxidative degradation of MXenes in the presence of NO2 gas limits their utility in effective NO2 detection. To address these challenges, we functionalize MXene surface with dopamine-conjugated carboxymethyl cellulose (CMC-DA). CMC-DA ligands enhance oxidation stability, promote strong adhesion to textile fibers, increase MXene loading, and enable selective interactions with NO2 and humidity via their catechol head and CMC tail, respectively. Pad-dried cotton e-textiles are used to demonstrate Joule heating and strain sensing capabilities, while dip-coated hemp e-textiles are employed to demonstrate gas and humidity sensing. **This was supported by Korea National University of Transportation in 2025.
