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.

A coating agent for oil seal comprising 10 to 90 parts by weight in total of fluororesin particles having a particle size of 2 m or less and filler particles other than fluororesin particles having a particle size of 0.5 to 30 m, and 10 to 40 parts by weight of a wax having a melting point of 40 to 160 C., based on 100 parts by weight of isocyanate group-containing 1,2-polybutadiene, and being prepared as an organic solvent solution, wherein the fluororesin particles are used at a ratio of 20 to 80 wt. % of the total filler amount. The coating agent for oil seal can improve abrasion resistance while maintaining the roughness of a coating surface to which the coating agent is applied.
