In solid electrolytes, the decrease in bond energies can typically be attributed to the rise in dielectric constant at greater plasticizer concentrations . Which dielectric is "best" really depends on your specific application, operating conditions, and which properties are most critical in your application. Many organic and inorganic materials are used for high voltage insulation purposes. A dielectric materials measurement can provide critical design parameter information for many electronics applications. When a current interacts with a dielectric (insulating) material, the dielectric material will respond with a shift in charge distribution with the positive charges aligning with the electric field and the negative charges aligning against it. solid dielectric materials: solid dielectric materials are used in all kinds of electrical apparatus and devices to insulate one'current carrying part from another when they operate at different voltages, a good dielectric should have low dielectric loss, high mechanical strength, should be free from gaseous inclusions, and moisture, and be Answer: There is no single "best" solid dielectric.
