Abstract:
1. A composite material having a high dielectric constant and high dielectric strength, the composite material comprising: a quadmodal distribution of high dielectric constant ceramic particles bonded together by a polymeric material, wherein the quadmodal distribution comprises at least one first ceramic particle having a first diameter in a first range between 40 μm and 220 μm, at least one second ceramic particle having a second diameter in a second range between 500 nm and 5 μm, and at least one third ceramic particle having a third diameter in a third range between 2 nm and 500 nm; and, wherein the polymeric material is polymerized in-situ from a polymeric precursor and binds directly to a surface of each of the high dielectric constant ceramic particles.
