Abstract
Aqueous dispersions of carbon nanotubes with poly(styrene sulfonate) were investigated over a range of pH and ionic strengths as a means of determining the potential for further application of the polymer as a protective agent for the tubes. The poly(styrene sulfonate) was found to be an effective dispersal agent, capable of reducing the size of the nanotube agglomerates within an aqueous solution and dispersing the tubes in a single-step process.
