Multi-Walled Carbon Nanotube NMP Dispersion ~5 wt% ATOMFAIR®

This NMP-based dispersion requires solvent-compatible handling equipment and controlled atmosphere processing to prevent solvent evaporation and nanotube agglomeration. The dispersion must be stored in sealed containers away from moisture and heat sources to maintain stability.

• Solvent compatibility: Use only NMP-compatible wetted materials for transfer and storage to avoid solvent degradation or contamination.
• Atmosphere sensitivity: Minimize exposure to ambient air during handling to prevent moisture uptake and nanotube aggregation.
• Temperature stability: Store below 25°C in a cool, dry area to maintain dispersion homogeneity and prevent solvent loss.

This procedure describes safe transfer and application of the NMP-based dispersion for coating or composite preparation. Proper mixing and degassing steps ensure uniform nanotube distribution and film quality.

Required Equipment: NMP-compatible syringe or pipette, Sealed glass vial with PTFE-lined cap, Ultrasonic bath or probe sonicator

1. Inspect dispersion
   Inspect the sealed container for any visible sedimentation or gelation before opening.
2. Redisperse nanotubes
   Sonicate the sealed vial in an ultrasonic bath for 10–15 minutes to redisperse any settled nanotubes.
3. Transfer dispersion
   Transfer the required volume using an NMP-compatible syringe or pipette under a fume hood.
4. Apply to substrate
   Apply the dispersion onto the target substrate using spin-coating, drop-casting, or doctor-blading as required.
5. Dry the film
   Dry the coated substrate at 80–120°C under vacuum or inert atmosphere to remove residual NMP.

Atomfair AF-CNTD-NDM is a research-grade multi-walled carbon nanotube dispersion in NMP at approximately 5 wt% solid content, offered in P1000 and P1800 model options for matching to coating, composite, electrode, and conductive-additive workflows. The evaluation centers on NMP solvent compatibility and confirming the nominal concentration before quantitative formulation.

Positive

• NMP dispersion for coating workflows: Supplied as multi-walled carbon nanotubes dispersed in NMP at approximately 5 wt%, this product can be matched to electrode, coating, conductive additive, and composite preparation workflows. Its liquid dispersion form is appropriate for formulating NMP-compatible slurries.
• Model variants for specification matching: The AF-CNTD-NDM series includes P1000 and P1800 model designations, enabling comparison of dimensional or concentration specifications before quotation. This supports matching the dispersion to the target experimental or formulation workflow.

Trade-offs

• Nominal concentration requires confirmation: The carbon nanotube content is listed as approximately 5 wt%, and the specification review step calls for confirmation of solid content, solvent, and viscosity details for the selected model. Quantitatively critical formulations should verify lot-specific values before use.
• NMP solvent compatibility must be verified: This product is specifically an NMP-based dispersion, and the quotation workflow requires confirmation of the solvent system against the target application. Laboratories planning aqueous or oil-based formulations must check solvent compatibility before ordering.
