Many inorganic ceramics have large permanent dipole moment, due to their chemical compositions and crystal structures. They typically exhibit very high dielectric permittivity up to a few thousands, in contrast to the low dielectric permittivity of polymer materials. However, with increasing demand of flexible, embedded, and miniaturized electronic devices, these ceramic materials alone fail to achieve similar success as in traditional electronics. Some reasons behind this include high brittleness, high mass density, low dielectric breakdown strength as well as poor processability of ceramic materials, and so on, compared with polymers.
