Nanocarbon Materials

Carbon nanomaterials are nanoscale structural systems composed entirely of carbon atoms and have become a core research area in materials science due to their unique physical and chemical properties and multidimensional structural characteristics. Classified by dimension and bonding type, these materials mainly include fullerenes, nanocarbon unit structures, carbon nanotubes, graphene, MXenes, carbon nanofibers, and nanodiamonds. Fullerenes, such as the highly symmetric C₆₀ molecule, consist of closed-cage sp²-hybridized carbon atoms with delocalized π-electrons that confer excellent electron acceptor properties; they hold promise for optoelectronic devices and supramolecular assemblies but face challenges in functionalization and scalable synthesis. Nanocarbon unit structures, including fundamental nanoscale building blocks like nanorings, exploit size effects and edge chemistry through functional group modifications to regulate photoluminescence, catalysis, and other properties, enabling atomic-level design of nanodevices. Carbon nanotubes (CNTs), one-dimensional tubular structures formed by rolled graphene sheets, exist as single-walled or multi-walled types and exhibit exceptional axial strength, electrical conductivity, and thermal conductivity; however, their poor dispersion requires dispersants that improve interfacial compatibility via π-π interactions or covalent modifications. Graphene is a two-dimensional honeycomb lattice of sp² carbon atoms with ultrahigh carrier mobility and mechanical strength, while its oxidized form, graphene oxide, produced by oxidative exfoliation, contains hydroxyl and epoxy groups, offering solution processability and chemical modifiability at the expense of reduced conductivity, which can be partially restored through reduction. MXenes, derived from the etching of MAX phases with the general formula Mn+1XnTx (where M is a transition metal, X is carbon, nitrogen, or boron, and T represents surface groups), display layered structures with high conductivity and hydrophilicity suitable for energy storage and electromagnetic shielding applications, although they face urgent challenges related to interlayer restacking. Carbon nanofibers (CNFs), fabricated via electrospinning or chemical vapor deposition, combine high surface area and flexibility, making them ideal for electrodes and filtration membranes. Nanodiamonds (NDs), synthesized through detonation methods and characterized by their sp³ hybridized carbon structure, possess extreme hardness and biocompatibility, with expanding applications in bioimaging and quantum sensing enabled by surface functionalization.
