MXenes are a rapidly expanding family of two-dimensional materials: transition-metal carbides, nitrides, and carbonitrides that combine the atomic thinness associated with graphene with the chemical versatility of complex ceramics. Typically produced by selectively etching layered MAX-phase precursors or related compounds, MXenes consist of metal-carbon or metal-nitrogen sheets whose surfaces are terminated with functional groups such as oxygen, hydroxyl, fluorine, or chlorine. This surface chemistry is central to their appeal: it enables high electrical conductivity, hydrophilicity, tunable electronic behavior, strong interfacial interactions, and surface functionalization, making MXenes unusually adaptable for device fabrication and nanocomposite design.
Their importance in nanoscience lies in the breadth of properties that can be engineered by changing metal composition, layer thickness, surface terminations, defects, interlayer spacing, and hybrid architectures. As a result, MXenes are being investigated for energy storage and conversion, electromagnetic interference shielding, sensors, water purification, catalysis, photothermal systems, biomedical technologies, and next-generation flexible electronics.
MXene conferences reflect this diversity. The field is served both by dedicated MXene meetings and by 2D-materials tracks within broader nanotechnology, energy-storage, materials-science, and electromagnetic-shielding programs. In the latter, MXene research is often distributed across synthesis, characterization, device, and application sessions rather than gathered under a single banner.
