How does the 1.28 wt% -COOH content relate to the >99.9% purity of these graphitized MWCNTs?
The purity >99.9% refers to the carbonaceous content of the multi-walled carbon nanotubes. The 1.28 wt% -COOH is a covalently attached functional group, not an impurity, so it does not detract from the purity specification. This allows high carbon purity with controlled functionalization for subsequent reactions.
Can these graphitized carboxyl MWCNTs be used directly in aqueous dispersion without additional surfactants?
The product is functionalized with carboxyl groups at 1.28 wt%, which can improve dispersibility in polar solvents. However, the source does not specify exact dispersion conditions; users should match the material form to their intended workflow and confirm compatibility through experimentation or by contacting technical support.
What information is required when requesting a quotation for bulk quantities of these MWCNTs?
When requesting quotation support, include nanotube wall type, functionalization, diameter/length range, package size, and quantity. Bulk quantity requirements should be confirmed via email to inquiry@atomfair.com.
This graphitized carboxyl multi-walled carbon nanotube material (OD 8-15 nm, length 10-50 µm, purity >99.9%, -COOH content 1.28 wt%) offers a balance of high purity and functionalization for dispersion and composite integration, but requires careful handling due to nanomaterial inhalation risks and batch-to-batch variability in functional group density.
Positive
- High purity with carboxyl functionalization: Purity >99.9% minimizes catalytic metal contamination, while 1.28 wt% -COOH groups enable covalent or hydrogen bonding in polymer composites and electrode formulations without requiring additional surface treatment.
- Graphitized structure for conductivity: Graphitization reduces structural defects and increases electrical conductivity, making this material suitable for conductive films, battery electrodes, and EMI shielding applications where low resistance is critical.
Trade-offs
- Nanomaterial inhalation hazard: As a dry powder with nanoscale diameter (8-15 nm), this material poses respiratory risks if aerosolized; handling requires fume hoods, HEPA filtration, and personal protective equipment to prevent inhalation exposure.
- Functional group density variability: The -COOH content of 1.28 wt% is a nominal value; actual functionalization density may vary between batches, requiring end-user verification for applications where precise surface chemistry is critical for dispersion or reactivity.
