How does the 0.15 wt% concentration and carboxylic functionalization affect the conductivity and processability of this SWCNT dispersion compared to higher concentrations or non-functionalized tubes?
The 0.15 wt% concentration is relatively low, which aids in uniform dispersion but may require optimization for percolation thresholds in conductive composites or electrodes. The carboxylic groups (-COOH) enhance dispersibility in water and provide reactive sites for further functionalization, but can slightly reduce intrinsic conductivity compared to pristine tubes. The product maintains >95% purity and an outer diameter of 1–2 nm with a length of 5–30 μm, supporting high aspect ratio for percolation networks.
Can this aqueous SWCNT dispersion be used directly in organic solvent-based coating formulations, or does it require a different solvent system?
This dispersion is aqueous and intended for water-based workflows. Direct mixing with organic solvents may cause aggregation. The source notes that aqueous, NMP, oil-based, paste, and slurry forms can be matched to specific workflows, but this particular variant is supplied as an aqueous dispersion. For organic solvent systems, a different model (e.g., NMP-based) may be required. Contact technical sales at inquiry@atomfair.com for solvent system matching.
This carboxylic-functionalized ultrapure SWCNT aqueous dispersion (0.15 wt%, OD 1-2 nm, length 5-30 µm, >95% purity) is evaluated for use in dispersion, composite, film, electrode, and conductivity research, with two model variations (P680 and P1100) offering selectable specifications for workflow matching.
Positive
- High purity and narrow diameter distribution: Purity >95% and outer diameter of 1-2 nm ensure consistent electronic properties and minimal amorphous carbon contamination for reproducible SWCNT-based device or composite fabrication.
- Carboxylic functionalization enables dispersion stability: Carboxylic groups on the SWCNT surface improve aqueous dispersibility and provide reactive sites for covalent functionalization, facilitating integration into polar solvent-based formulations or composite matrices.
Trade-offs
- Low solid content limits bulk processing: At 0.15 wt% SWCNT content, the dispersion is dilute, requiring larger volumes or concentration steps for applications needing higher nanotube loading, such as conductive coatings or high-density electrodes.
- Aqueous solvent restricts solvent compatibility: The water-based dispersion may not be directly miscible with organic solvents or hydrophobic polymer matrices, necessitating solvent exchange or surfactant addition for non-aqueous processing workflows.
