SWCNT Slurry| Single-Walled Carbon Nanotube Conductive Additive
Lower percolation threshold than carbon black and MWCNT.
Introduction
Single-Walled Carbon Nanotube Dispersion
SWCNT slurry is a high-conductivity, pre-dispersed formulation of single-walled carbon nanotubes. It provides fast, uniform dispersion in plastics, coatings and battery materials, enabling ultra-low loading, stable resistivity and clean processing in water or NMP.

Product feature
Introduction
Our SWCNT slurry is formulated using high-aspect-ratio single-walled carbon nanotubes (eDIPS process). Through proprietary dispersion technology, the CNT network remains stable and uniform in water, NMP, ethanol and mixed systems. It is designed for ESD plastics, conductive coatings, printed electronics and battery electrode additives.
- Excellent dispersibility in water, NMP and ethanol
- Long-aspect-ratio SWCNTs preserved during dispersion
- Ultra-low loading to achieve target resistivity
- Compatible with PC/ABS, PA, PBT, TPU, epoxy, PU and more
- Customizable concentrations and solvent systems
- Cleaner, easier processing vs. dry CNT powders
Technical FAQ
1. What is SWCNT slurry?
A ready-to-use dispersion of single-walled carbon nanotubes for plastics, coatings, and battery applications.
2. Why is it better than CNT powder?
Pre-dispersed slurry avoids agglomeration, improves consistency, and reduces mixing time.
3. What is the typical dosage?
ESD plastics: 0.02–0.1% depending on resin and resistivity target.
4. Is it compatible with PC/ABS and PA?
Yes. It performs well in PC/ABS, PA6, PA66, PBT, TPU, PU, and epoxy systems.
