“Flocculation Dynamics and Reinforcement of Elastomer Nanocomposites with Conductive Fillers: A Combined Rheological and Dielectric Analysis”
Abstract:
The flocculation dynamics of carbon black filled elastomer melts is investigated by dielectric relaxation spectroscopy in the frequency range from 0.1 Hz up to 10 MHz during oszillatory shearing in a plate-plate rheometer [1]. It is demonstrated that during heat treatment at low strain amplitude, a pronounced flocculation of filler particles takes place leading to a successive increase of the shear modulus and dc-conductivity…
