How do the outer diameter (30-50 nm) and length (<10 µm) of these carboxylic MWCNTs affect the achievable aspect ratio and its impact on percolation in a conductive composite?
The outer diameter of 30-50 nm and length <10 µm yield an aspect ratio in the range of 200-333. This high aspect ratio facilitates electrical percolation at low filler loadings, though exact performance depends on dispersion quality. The technical specifications confirm these dimensional ranges.
What is the functional group on these multi-walled carbon nanotubes and how does it influence compatibility with polar solvents for electrode or composite preparation?
These are carboxylic multi-walled carbon nanotubes, meaning the surface is functionalized with carboxyl groups (-COOH). This functionalization enhances dispersibility in polar solvents like water, alcohols, and certain polymer matrices, making them suitable for electrode slurry and composite formulations. The product type confirms the carboxylic functionalization.
What is the recommended procedure for ordering bulk quantities of these carboxylic MWCNTs?
Bulk quantity requirements should be confirmed when requesting quotation support. The product page advises contacting the technical sales team at inquiry@atomfair.com with details on nanotube wall type, functionalization, diameter/length range, package size, and quantity. The procurement note specifies that bulk requirements need confirmation.
This carboxylic multi-walled carbon nanotube material (OD 30-50 nm, length <10 µm, purity >95%) is evaluated for use in dispersion, composite, electrode, and conductivity research workflows, where the carboxyl functionalization provides reactive sites for covalent grafting or dispersion stabilization in polar media.
Positive
- Carboxyl functionalization for reactivity: The carboxylic acid groups enable covalent attachment to polymers, biomolecules, or metal oxides, improving interfacial bonding in composite and electrode formulations compared to pristine CNTs.
- High purity >95% for consistent results: Purity exceeding 95% minimizes amorphous carbon and metal catalyst residues, reducing batch-to-batch variability in conductivity and surface chemistry experiments.
Trade-offs
- Short length limits percolation in thick films: Length <10 µm may reduce electrical percolation efficiency in high-thickness composite layers or porous electrodes compared to longer MWCNTs (>20 µm).
- Bulk quantity confirmation required before ordering: The procurement note indicates that bulk volume availability must be verified with the supplier, introducing a lead-time risk for scale-up projects.
