| Abstract Scope |
MXenes are a class of 2D materials with a general formula Mn+1XnTx, where M is a transition metal (in this study, titanium), X is carbon and/or nitrogen, and Tx denotes surface termination groups such as -OH, -F, -O and –Cl. Due to their exceptional electrical conductivity (~20,000 S/cm), hydrophilicity, and surface tunability, MXenes are emerging as promising candidates in energy storage, sensing, and more. However, their practical implementation is hindered by oxidization in aqueous and high temperature environments. In this study, we investigate the surface functionalization of Ti3C2Tx MXenes (derived from Ti3AlC2 MAX) with organic amine-based ligands. These molecules, with their high redox activity, strong π–π interactions, and ability to form protective polymeric coatings, enable the development of organic–inorganic MXene hybrids. This hybrid shows greater stability against oxidation and high temperatures. Our work aims to provide fundamental insights into how these modified MXenes undergo phase transitions. |
