MXenes are a large family of two-dimensional materials with the general formula of Mn+1XnTx (n = 1-4), where M is a transition metal, X is carbon and/or nitrogen, and Tx denotes surface functional groups (-OH, -O, -F, etc.). MXenes exhibit several interesting properties such as metallic electrical conductivity, good aqueous dispersion stability, tunable work function, etc., which expanded their application potential to various fields. However, the spontaneous oxidation of MXene due to interaction with oxygen and water is a critical concern for the long-term storage of synthesized MXene and the ambient stability of MXene-based devices. In addition, good dispersion stability of MXenes is restricted to aqueous medium, which is another concern as most of the solution-based approaches prefer volatile organic solvents. Hence, our research group is mainly devoted to the synthesis of high-quality MXene nanosheets and functionalize their surface with organic molecules, polymers, nanomaterials to obstruct the spontaneous oxidation of MXenes as well as to enable the excellent dispersion stability in various organic solvents. Further, we test the application potential of developed high quality aqueous and organic solvent-based MXene inks in various fields such as Photodetectors, Printed Electronics (logic gates and memory cells), E-textiles/Hydrogels for sensing applications, etc.
