Abstract
Two-dimensional (2D) MXenes, an emerging class of materials, demonstrate an exceptional combination of features such as modifiable surface chemistry, high electronic conductivity, and strong mechanical strength. These qualities make them suitable for numerous applications in various fields. While their electronic and mechanical properties have been extensively studied, their IR characteristics remain poorly understood. This lack of understanding limits the potential use of MXenes in IR-related technologies. The ultimate goal of the work is to provide a step toward closing this knowledge gap and deepen the understanding of the fundamentals of the IR properties of MXenes, including absorption, transmission, reflection, and emissivity. This knowledge is crucial for the rational design of MXenes with predicted IR properties for targeted applications such as sensors, thermal management devices, stealth technologies, and energy scavengers. The strategy is multi-faceted, employing a variety of cutting-edge IR spectroscopic methods to uncover the complex elements of vibrational dynamics, chemical reactivity, and interface properties of MXenes. Additionally, the prediction models will be developed, linking MXene composition to the IR trends observed, thereby guiding a more informed and targeted approach to materials design. A systematic investigation of how critical parameters of MXene compositions (such as transition metals, layer number, and surface terminations) and environmental factors (like room temperature and high temperature) affect their IR performance will be conducted. This comprehensive study will not only significantly expand the understanding of the intrinsic IR characteristics of MXenes but also provide valuable guidelines for their potential use in various IR applications. Finally, this study aims to unlock the full potential of MXenes in applications that require on-demand control of IR interactions, helping to develop next-generation materials and devices.
