A class of materials is provided that has dielectric constants
greater than 10⁵
. The super dielectric materials (SDM) can
be generated readily from common, inexpensive materials.
Various embodiments include a porous, electrically insulating
material, such as high surface area powders of silica or
titania, mixed with a liquid containing a high concentration
of ionic species. In some embodiments, high surface area
alumina powders, loaded to the incipient wetness point with
a solution of boric acid dissolved in water, have dielectric
constants greater than 4 x 10 ⁸.
