How does the carboxylic functionalization affect the electrical conductivity of these multi-walled carbon nanotubes compared to pristine MWCNTs?

Carboxylic functionalization introduces -COOH groups that disrupt the sp2 carbon lattice, potentially reducing intrinsic electrical conductivity relative to pristine MWCNTs. This trade-off is intentional for applications requiring enhanced dispersibility in polar solvents and polymer matrices, as indicated in the material matching notes for dispersion, electrode, and composite workflows.

What solvents are recommended for dispersing carboxylic multi-walled carbon nanotubes?

The product description does not specify solvents, but the carboxylic functionalization improves compatibility with polar solvents such as water, ethanol, and DMF. The material is intended for dispersion, composite, and electrode workflows, and users should select solvents based on their specific application. Technical support is available for solvent recommendations.

What does the >95% purity specification mean for the performance of these carbon nanotubes?

The >95% purity indicates less than 5% non-CNT content, including residual catalyst particles and amorphous carbon. This high purity supports consistent performance in sensitive applications like electrode fabrication and composite preparation, where impurities can cause variability. The specification is reviewed during material matching for the selected CNT powder.

This carboxylic-functionalized multi-walled carbon nanotube (OD 20-30 nm, length 10-30 μm, >95% purity) is assessed for its defined geometry and functionalization, which support dispersion, composite, electrode, and conductivity research applications as stated in the material matching notes.

Positive

  • Carboxyl functionalization: The carboxylic acid groups on the nanotube surface enable compatibility with dispersion, electrode, composite, and conductivity workflows, as explicitly indicated in the selection and matching notes.
  • Defined dimensions and purity: The specified outer diameter (20-30 nm), length (10-30 μm), and purity (>95%) provide consistent dimensional and compositional characteristics for model matching in experimental formulations.
