摘要:
A dielectric material suitable for use between electrodes of a capacitor includes dipole-impregnated fullerenes able to increase a dielectric constant of the dielectric material in order to enhance the energy storage capacity of the capacitor is provided. The dielectric material includes buckminsterfullerenes each having a dipole molecule impregnated within the buckminsterfullerene, the dipole molecules within the buckminsterfullerenes able to rotate and align with forces of an electric field when in the presence of the electric field so that, when in use between the electrodes of the capacitor, they counteract the electric field between the electrodes and increase the energy storage capacity of the capacitor.

The present invention includes an apparatus for generating an inorganic polymer electret in a colloidal state, the inorganic electret in a colloidal state itself, and applications for the inorganic electret in a colloidal state. The invention includes a method for generation of a colloidal silica particle which is dipolar in that it is positively charged in the nucleus and negatively charged on the outer surface leaving a net negative charge to the particle. The apparatus includes the ability to control particle size, uniformity, consistency, hydration, and three dimensional structure which is desirable for various applications.

摘要:
An electret-structure encompasses a fluorine-resin film 21, an electrode 22 formed on one surface of the fluorine-resin film 21, and a silica layer 21 formed on another surface of the fluorine-resin film 21. The silica layer 21 is implemented by a plurality of island-shaped silica regions 201 for covering the fluorine-resin film 21 in a topology such that the island-shaped silica regions 201 are isolated from each other. And negative charges are deposited on the island-shaped silica regions 201. The static-induction conversion element with the electret-structure 1 can be mounted on a substrate by reflow-process through Pb-free solder.
