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
