The mechanism of CNT dispersion in rubber matrices was studied by the analysis of the morphological development on macro- and microscale by optical and electron microscopy as well as atomic force microscopy. The results from the morphological assessment were correlated to the time dependent electrical conductance measured directly during the mixing process. It becomes obvious that the conductance-time curves measured during the mixing process of CNT-rubber compounds show basically the same course like for carbon black (CB) filled rubber mixtures. The time-dependent stages of the electrical conductance have been correlated to the degree of CNT dispersion, successfully determined by microscopical methods. The investigation shows that CNT can be controlled introduced into rubber matrix materials using the method of online measured electrical conductance during the mixing process.
