dc.description.abstractThe present invention is directed to polymer-ceramic composites having high dielectric constants formed using polymers containing a metal acetylacetonate (acacs) curing catalyst. In particular, it has been discovered that 5 weight percent Co(III) acac can increase the dielectric constant of DER661 epoxy by about 60%. The high dielectric polymers are combined with fillers, preferably ceramic fillers, to form two phase composites having high dielectric constants. Composites having about 30 to about 90% volume ceramic loading and a high dielectric base polymer, preferably epoxy, have been discovered to have a dielectric constants greater than about 60. Composites having dielectric constants greater than about 74 to about 150 are also disclosed. Also disclosed are embedded capacitors with capacitance densities of at least 25 nF/cm2, preferably at least 35 nF/cm2, most preferably 50 nF/cm2. Methods to increase the dielectric constant of the two phase composites having high dielectric constants are also provided.
