Research Abstract |
The three-dimensional (3D) morphology of particulate fillers embedded in a rubbery matrix was examined by transmission electron microtomography (TEMT). Two types of nano-fillers, i.e., carbon black (CB) and silica (Si) nano-particles, were used as the nano-fillers. Although the CB and Si nano-particles were difficult to distinguish by conventional transmission electron microscopy (TEIM), they appeared different by TEMT; the CB and Si nano-particles appeared to be hollow and solid particles in the cross-sectional images of the TEMT 3D reconstruction, respectively, demonstrating that TEMT itself provided a unique particle-discriminative function. The nano-particles were found to than aggregates in the matrix. It is intriguing that each aggregate was made of only one species; not a single aggregate contained both the CB and Si nano-particles A particle-packing algorithm was developed to estimate the positions of each primary nano-particle inside the aggregates.
