The separation of single-wall carbon nanotubes in liquid phases can be achieved by a number of different processes, yet the molecular mechanism behind any one of the separation processes is not fully understood. This opportunity aims at revealing separation mechanisms by studying the modulating effect of pH, ionic strength, and redox on the separation outcome, paying special attention to the reorganization of dispersant layers triggered by the modulating factors.
