Abstract
We report a dispersion state of concentrated multiwalled carbon nanotube (MWCNT) suspensions depending on their iterative milling process. The rheological properties of concentrated suspensions prepared with different milling times were measured using a Couette-typed rotation rheometer, and their electrical characteristics were investigated via an LCR meter. The relationships of the rheological and electrical properties with the dispersion state of the MWCNT were examined. The results of both the rheological and electrical measurements indicated that the de-bundling and dispersion of the MWCNT induced by the iterative milling yielded a percolation microstructure and an electrically conductive structure.
