MXene-Wood Composites: A Review of Fabrication, Properties, Applications, and Future Prospects

Abstract

MXene is a cationic 2D material made of transition metal carbides known for its diverse structure and multifunctionality. It faces challenges like stacking, oxidation, and weak mechanical properties that limit its use. By integrating MXene with self-supporting porous materials, it can be stabilized and converted from fragile 2D sheets to strong 3D structures. Wood, due to its natural structure and stability, is ideal for depositing MXene, which adheres to wood via adsorption, hydrogen bonding, or reactions with wood fibers. New MXene-wood composites with improved functions have been created and show great potential for interdisciplinary research. This review covers preparation methods, applications, potential development, and challenges of MXene-wood composites, aiming to provide a research framework and progressive direction for their future development.
