2 . The electronic device of claim 1 , wherein the carbon nanodomains comprise graphene.

3 . The electronic device of claim 1 , wherein the carbon nanodomains constitute between 5-40 vol % of the nanocomposite.

4 . The electronic device of claim 1 , wherein the carbon nanodomains comprise graphene, and wherein the graphene is in the form of single layers, stacks of 2-4 layers, or stacks of more than 4 layers, or combinations thereof.

5 . The electronic device of claim 1 , wherein the nanocomposite is a component in a dielectric material, wherein the dielectric material is a film.

6 . The electronic device of claim 1 , wherein the carbon nano domain volume does not constitute an electrical conduction path.

7 . The electronic device of claim 1 , wherein the carbon nanodomains have dimensions of less than 20 nm.

8 . The electronic device of claim 1 , wherein the carbon nanodomains are thermally formed in situ during formation of the insulating ceramic matrix.

9 . The electronic device of claim 1 , wherein the nanocomposite is further disposed within a second phase, the second phase comprising a polymer, ceramic, or glass material matrix.

10 . The electronic device of claim 1 , wherein the carbon nanodomains constitute between 5-40 vol % of the nanocomposite and do not constitute an electrical conduction path.

11 . The electronic device of claim 1 , wherein the carbon nanodomain volume does not constitute an electrical conduction path, and wherein the volume and distribution of carbon nanodomains provide a permittivity of the nanocomposite that is greater than or equal to 200.

12 . The electronic device of claim 1 , wherein the nanocomposite is further disposed within a second phase, the second phase comprising a polymer, ceramic, or glass material matrix, and wherein the carbon nanodomains comprise graphene that are single layers or are stacks of 2-4 layers, and wherein the volume and distribution of the carbon nanodomains provide a permittivity of the nanocomposite that is greater than or equal to 200.

13 . The electronic device of claim 1 , wherein the nanocomposite is further disposed within a second phase, the second phase comprising a polymer, ceramic, or glass material matrix, and wherein the carbon nanodomains comprise graphene that forms stacks of more than 4 layers, and wherein the volume and distribution of carbon nanodomains provide a permittivity of the nanocomposite that is greater than or equal to 200.

14 . The electronic device of claim 1 , wherein the electronic device is selected from: a capacitor; a hybrid electrochemical battery capacitor; an RF-reactive circuit element; an RF filter; a DRA-type RF antenna; an energy storage device; a pulse power system; a capacitor energy storage device; a distributed capacitor in a microdevice; a component in a field effect transistor (FET); and an integrated component in a very large system integration (VLSI).

15 . A method for making the electronic device of claim 1 , wherein the nanocomposite is prepared via a method comprising the step:
(a) pyrolzing a composition comprising a precursor or blend of precursors comprising organic and inorganic moieties such that carbon nanodomains are grown in-situ during formation of the insulating ceramic matrix in a controlled content fashion and form the nanocomposite.
