MXene Multidimensional structure Restacking Carbon composite

PDF

MXene is a two-dimensional transition metal-based material with high electrical conductivity, large specific surface area, and diverse surface functional groups. It has attracted attention in applications such as energy storage, catalysis, and electromagnetic interference (EMI) shielding. However, issues such as interlayer restacking, oxidation, and limited mechanical flexibility restrict its performance when used alone. To address these limitations, composite design strategies combining MXene with multidimensional structures have been actively studied. Zero-dimensional (0D) nanoparticles enhance interfacial bonding and structural stability by dispersing between MXene layers, improving EMI absorption and interfacial reactivity. One-dimensional (1D) structures provide charge transport pathways and maintain interlayer spacing, enhancing flexibility and electrochemical performance. Two-dimensional (2D) materials prevent restacking and support efficient ion and electron transport, improving both rate capability and capacity. Three-dimensional (3D) porous structures contribute to structural stability and provide EMI shielding and thermal management functions. This review summarizes recent research trends on MXene-based multidimensional carbon composites, focusing on structural characteristics and application potential. Strategies for composite design and future directions are also discussed.
