What is the significance of the outer diameter range of 2-4 nm for these double-walled carbon nanotubes?
The outer diameter of 2-4 nm is a key specification for double-walled carbon nanotubes, as it influences the nanotube's electronic properties and aspect ratio. This specific range supports model matching against the required experiment or formulation workflow, such as composite or conductivity research.
What application workflows are these carboxylic double-walled carbon nanotubes suitable for?
The product is intended for dispersion, composite, film, electrode, conductivity, or nanocarbon research workflows. The carboxylic functionalization allows the material to be matched to these specific applications, as noted in the selection and use notes.
What information must be confirmed before ordering these carbon nanotubes?
Before quotation, the user must confirm the nanotube wall type, outer diameter, length, purity, functional group, and package size. Additionally, bulk quantity requirements should be confirmed with the technical sales team, as stated in the procurement notes.
This carboxylic-functionalized double-walled carbon nanotube material (OD 2-4 nm, length ~50 µm, purity >60%) is evaluated for research applications requiring enhanced dispersibility in polar solvents or polymer matrices, with the carboxyl groups providing reactive sites for covalent functionalization. The moderate purity and broad dimensional distribution impose constraints on reproducibility in precision electronic or optical applications.
Positive
- Carboxyl functionalization for dispersion: The carboxylic acid groups improve dispersibility in polar solvents and enable covalent bonding with polymers or biomolecules, facilitating integration into composite, electrode, or sensor workflows.
- Double-walled structure balances properties: Double-walled carbon nanotubes offer a compromise between single-wall electrical performance and multi-wall mechanical robustness, suitable for conductive films and reinforced composites.
Trade-offs
- Purity >60% limits precision use: The >60% purity indicates significant amorphous carbon and catalyst residue content, which may introduce variability in electronic transport or catalytic studies requiring high-purity material.
- Broad dimensional distribution affects reproducibility: The outer diameter range of 2-4 nm and length of ~50 µm represent a polydisperse sample, requiring batch characterization for experiments sensitive to nanotube geometry.
