Nanotube Dispersion: Carbon Nanotubes in the Liquid Phase: Addressing the Issue of Dispersion (Small 9/2012)

The image features the dispersion of carbon nanotubes (CNTs) in liquids and the clarification of the term and process. Based on the controversy existing in the scientific community, research involving the dispersion of CNTs in liquids, particularly in water, are analyzed and reviewed. According to fundamental approaches and concepts, the term dispersion is shown to be more appropriate than the term solution. In addition, the dispersion in different media, the stability, and the interactions between CNTs and solvents are evaluated. The image illustrates the dispersion of CNTs in a liquid both in the agglomerated and well-dispersed state.
