MXenes are a class of two-dimensional materials with potential applications in fields such as thermal management and high-temperature materials. In this talk, I focus on three key aspects: (1) Synthesis of MXenes and their surface properties, (2) Assembly of MXene into multiscale structures, and (3) Applications of MXene. In particular, the thermal evolution of Ti3C2Tx MXene during annealing and the grafting behavior of amine ligands for MXene surface modification will be introduced. The thermal decomposition behavior of MXene is explored using X-ray photoelectron spectroscopy (XPS) and two-dimensional correlation spectroscopy (2D-COS), providing insights into its structural changes, providing practical information for thermal applications of MXene. In addition, surface modification strategies are employed to enhance MXene's stability and dispersibility. Oleylamine (OAm) is grafted onto Mxene nanosheets, resulting in improved oxidation and dispersion stability. The modified Mxene exhibits excellent solution processability and coating performance. The potential of OAm-MX as a heating element is investigated, leading to the development of a scalable electrothermal heating membrane with high efficiency. These advancements broaden the applications of MXene in thermal management and water desalination.
