Abstract

A straightforward method is presented for characterizing the quality of carbon nanotube (CNT) dispersions using scanning electron microscopy (SEM) imaging of samples prepared using a unique procedure, which successfully prevents re-coagulation of the CNTs during the evaporation of the dispersant. The images obtained more accurately reflect the status of the bulk dispersion in the liquid state. This method can be used to comparatively analyze the degree of disaggregation and the extent of tube breakage following a dispersion protocol in either aqueous or non-aqueous solutions, with or without surfactants, and regardless of the original condition of the CNTs.
