Abstract

!Dielectric constant and morphology of BaTiO3-polymer composite films were studied as a function of the filler concentration. The morphology of the films was examined using laser scanning confocal microscopy, which is capable to measure small particle distributions in more details than conventional microscopy. The thin-slice images allowed us to visualize the micron-size particles and the polymer between them nondestructively. We have found that, although BaTiO3 particles appear to form clusters at low filler concentrations, the cluster formation does not affect the dielectric constant of the composites.
