VOLTAGE SWITCHABLE DIELECTRIC MATERIAL HAVING A QUANTITY OF CARBON NANOTUBES DISTRIBUTED THEREIN
One or more embodiments provide for a composition that includes (i) organic material that is conductive or semi-conductive, and (ii) conductor and/or semiconductor particles other than the organic material. The organic material and the conductor and/or semiconductor particles are combined to provide the composition with a characteristic of being (i) dielectric in absence of a voltage that exceeds a characteristic voltage level, and (ii) conductive with application of the voltage exceeding the characteristic voltage level.
1 . A voltage switchable dielectric material having a quantity of carbon nanotubes distributed therein.
2 . The voltage switchable dielectric material of claim 1 , further comprising a binder, and wherein the quantity of carbon nanotubes is distributed as part of the binder.
3 . The voltage switchable dielectric material of claim 2 , further comprising titanium dioxide distributed in the binder.
4 . A voltage switchable dielectric material formed by:
creating a mixture comprising (i) a binder that is dielectric, (ii) metallic and/or inorganic conductor or semi-conductor particles, and (iii) conductive or semi-conductive organic material that is distributed as either a solvent soluble or as nano-scale particles in the mixture, wherein creating the mixture includes using a quantity of each of the binder, the metallic and/or inorganic conductor or semi-conductor particles, and the organic material so that the mixture, when cured, is (i) dielectric in absence of a voltage that exceeds a characteristic voltage, and (ii) conductive in presence of the voltage that exceeds the characteristic voltage; and
curing the mixture.
