The invention relates to a high-dielectric constant metal/ceramic/polymer composite material and a method for producing an embedded capacitor. As ceramic particles having a relatively small size are bound to the surface of metal particles having a relatively large size by mixing, the occurrence of percolation can be prevented without coating the metal particles, and at the same time, the capacitance of an embedded capacitor can be increased. In addition, a process for coating the surface of the metal particles can be omitted, thus contributing to the simplification of the overall preparation procedure.
A composite dielectric material comprising a resin, metal particles and ceramic particles wherein the ceramic particles are bound to the surface of the metal particles.
A method for preparing a composite dielectric material by mixing 1-30% by volume of metal particles and 1-40% by volume of ceramic particles in 30-98% by volume of a resin, and ball milling the mixture to bind the ceramic particles having a relatively low ductility to the metal particles have a relatively high ductility.
