Abstract: Disclosed herein is a method of: placing between a cooling element and an opposing surface a slurry of: a dielectric powder containing barium titanate, a dispersant, a binder, and water; maintaining the cooling element at a temperature below the opposing surface to cause the formation of ice platelets perpendicular to the surface of the cooling element and having the powder between the platelets; subliming the ice platelets to create voids; sintering the powder to form the dielectric material; and filling the voids with the polymeric material. The process can produce a composite having: a sintered dielectric material of barium titanate and platelets of a polymeric material embedded in the dielectric material. Each of the platelets is perpendicular to a surface of the composite.
