Abstract
A dielectric film includes an elastomer and nanoparticles dispersed in the elastomer while chemically bound to the elastomer. The nanoparticles have cyano groups and are manufactured by a sol-gel process using an organometallic compound. A method for manufacturing a dielectric film includes: producing a chelate compound of an organometallic compound; producing a sol of metallic oxide particles having cyano groups by adding a silane coupling agent having a cyano group, an organic solvent, and water to the chelate compound; preparing a mixed solution by mixing the sol of the metallic oxide particles having cyano groups and a polymer solution containing a rubber polymer having a functional group capable of reacting with a hydroxy group; and forming a dielectric film by applying the mixed solution to a substrate and by curing a coating film.
