Evaluation of carbon nanotubes dispersion in aqueous ...

Double-walled carbon nanotube (DWCNT) aqueous dispersions are produced by surfactant-assisted ultrasonication to break down bundles and ensure stability, yielding homogeneous liquids suitable for composites and electronics. Common, high-performance dispersions are created using purified DWCNT powder in water with surfactants such as sodium cholate (SC), Pluronic-P123, or SDS to prevent re-agglomeration.

Preparation Method: Involves two-step surfactant-assisted, tip-sonication to break down aggregates into individual nanotubes or small bundles.
Dispersion Agents: Effective agents include surfactants like sodium cholate (SC) and block copolymers such as Pluronic P123 or F127, which create steric/electrostatic forces that overcome van der Waals attraction.
Stability & Quality: High-quality dispersions, indicated by Raman G/D ratios (>30), show high crystallinity and long-term stability, often resulting in strong, electrically conductive thin films.
Customization: Customized concentrations, typically up to 1.0 wt% or higher (up to 1.8 wt% with specialized techniques), can be achieved for applications like conductive coatings, fiber fabrication, and energy storage.
Applications: Used in conductive fillers for composites, supercapacitors, and advanced electronics, especially where both strength and conductivity are required.
