Abstract

Three-dimensional (3D) structures of rubber containing two kinds of nano-filler, i.e., carbon black (CB) and silica (Si) particles, have been studied by transmission electron microtomography (TEMT) together with electron energy loss spectroscopy (EELS). In a digital slice obtained from the 3D reconstructed TEMT data, two kinds of particles were clearly distinguished. Some structural parameters, e.g. particle size and their distributions, were evaluated independently for the CB and Si particles from the 3D reconstruction of the TEMT. The fractal dimension obtained from the 3D image indicated that both CB and silica nanoparticles were aggregated by the "cluster- cluster aggregation" mechanism.
