Abstract

$BaTiO_3$/epoxy composites can be applied as the dielectric materials for embedded capacitors. The effects of the degree of $BaTiO_3$ particle agglomeration on the dielectric properties of $BaTiO_3$/epoxy composites were investigated in the present study. The degree of particle agglomeration was controlled by the milling of the agglomerated particles. The size and content of the agglomerated $BaTiO_3$ particles decreased with an increase in the milling time. The dielectric constants and polarizations of $BaTiO_3$/epoxy composites abruptly decreased with the increase of the milling time. It was concluded that the dielectric constants and polarizations of $BaTiO_3$/epoxy composites decreased as the degree of particle agglomeration decreased. The degree of agglomeration of $BaTiO_3$ particles turned out to be a very influential factor on the dielectric properties of $BaTiO_3$/epoxy composites.
