Abstract

Using the dielectrophoretic effect, submicron BaTiO3 powders dispersed in an uncured silicone elastomer could be redispersed into an aligned composite. The cured and aligned composites were microtomed into thin sections and characterized using electron and optical microscopy. Dielectric characterizations of the aligned composites were also studied and modelled using the conventional dielectric mixing rules. Both the microscopy and dielectric characterization suggested the alignment of BaTiO3 particles in a quasi 1-3 connectivity pattern parallel to the direction of the applied electric field.
