Products
Nanomaterials encompass a vast and rapidly expanding domain of materials science, defined by the manipulation of matter at length scales where quantum confinement, surface dominance, and size-dependent phenomena unlock properties unattainable in bulk counterparts. With at least one dimension in the 1-100 nanometer range, nanomaterials exhibit extraordinary optical, electronic, mechanical, catalytic, and biological behaviors that have propelled them from laboratory curiosities into critical enablers of modern technology. The global nanomaterials market surpassed $52 billion in 2024 and is projected to exceed $146 billion by 2034, growing at a compound annual rate of approximately 10.8%, driven by accelerating demand from electronics, energy, healthcare, environmental remediation, and advanced manufacturing sectors worldwide.
The classification of nanomaterials by dimensionality provides a useful conceptual framework: zero-dimensional materials such as quantum dots and fullerenes confine charge carriers in all three spatial directions; one-dimensional nanomaterials including carbon nanotubes and nanowires enable directional transport and exceptional aspect ratios; two-dimensional materials like graphene, MXenes, and transition metal dichalcogenides offer atomically thin platforms for electronic and photonic innovation; and three-dimensional hierarchical structures such as metal-organic frameworks and aerogels combine nanoscale features with macroscopic processability. At Eata Nanomaterials, our portfolio spans this entire dimensional spectrum, supplying researchers and industrial developers with the precisely characterized materials required to push the boundaries of nanotechnology across diverse application domains.

Carbon-Based Nanomaterials
Carbon-based nanomaterials commanded approximately 32% of global nanomaterials revenue in 2024, representing roughly $16.9 billion in market value. Their dominance reflects the remarkable versatility of sp²-hybridized carbon allotropes: graphene delivers unprecedented electrical conductivity and mechanical strength in atomically thin layers; carbon nanotubes provide high-aspect-ratio conductive pathways and reinforcing fibers; fullerenes offer unique cage-like architectures for drug delivery and organic electronics; and carbon quantum dots bring biocompatible fluorescence to sensing and bioimaging applications. Our carbon nanomaterials portfolio encompasses all major allotropes with options for surface functionalization, dispersion, and composite integration.
Our high-quality graphene product line encompasses chemical vapor deposition (CVD) grown monolayer and few-layer graphene transferred to diverse substrates, as well as liquid-phase exfoliated graphene dispersions for scalable composite and coating applications. CVD graphene on copper foil achieves optical transmittance exceeding 97% with sheet resistance below 300 Ω/sq, suitable for transparent conductor research and flexible electronics prototyping. Liquid-phase exfoliated products provide gram-scale quantities of few-layer graphene flakes with lateral dimensions tunable from submicron to over 10 μm.
CVD Graphene, Graphene-Like Materials
Beyond single-crystal monolayer graphene, we supply CVD-grown bilayer and trilayer graphene with controlled stacking configurations (AB and twisted), hexagonal boron nitride (hBN) as an atomically flat dielectric substrate for van der Waals heterostructure assembly, and fluorographene for bandgap engineering studies. Large-area graphene films on PET, SiO₂/Si, and custom substrates are available for device fabrication research.
The graphene-like series expands the two-dimensional materials portfolio beyond carbon to include silicene, germanene, and phosphorene analogues—materials predicted to exhibit tunable bandgaps, high carrier mobilities, and unique topological properties. These emerging materials are supplied as epitaxial films on metal substrates or as mechanically exfoliated flakes suitable for fundamental transport and optical characterization.
Defect-Free Single-Crystal Graphene and Graphene-Like Materials (Mechanical Exfoliation)
For researchers requiring the highest structural perfection, we provide defect-free single-crystal graphene flakes prepared by mechanical exfoliation from highly oriented pyrolytic graphite (HOPG) using the micromechanical cleavage technique pioneered by Geim and Novoselov. These flakes exhibit room-temperature carrier mobilities exceeding 10,000 cm²/V·s, making them indispensable for quantum Hall effect studies, nanoelectromechanical device fabrication, and scanning probe microscopy calibration. Graphene-like mechanically exfoliated flakes of MoS₂, WS₂, and hBN are also available.

MXenes, a family of two-dimensional transition metal carbides, nitrides, and carbonitrides with the general formula Mₙ+₁XₙTₓ (where Tₓ represents surface terminations), have attracted explosive research interest since their first report in 2011. With over 50 compositions experimentally synthesized and hundreds more predicted computationally, MXenes offer a unique combination of metallic conductivity, hydrophilic surfaces, and tunable electrochemical properties. Ti₃C₂Tₓ dispersions at concentrations up to 50 mg/mL enable flexible film casting, while Nb₂CTₓ and Mo₂TiC₂Tₓ target specific applications in electromagnetic interference shielding and catalysis respectively.
