The suspensions are produced using two types of industrially available CNTs (Nanocyl 3150 and 7000) and using two different dispersion techniques, namely 3-roll milling and sonication. In-situ optical microscopic analysis and electrical conductivity measurements have been conducted. It is shown that despite using CNTs with similar aspect ratios, the dispersability of the raw material and the time stability of the suspensions are quite different. Additionally, viscosity measurements are used to evaluate the initial dispersion quality and time stability.en0014-305720111120692077ElsevierAgglomerationCarbon nanotubesDispersionElectrical conductivityNanofillersRheological propertiesChemieJournal Article10.1016/j.eurpolymj.2011.07.022Journal Article
