Enhancing dielectric constants of elastomers using electric fields
Abstract:
An enhanced elastomer molding process applies an electric field to an elastomer doped to include dielectric ceramic particulates inserted in a cavity of a mold while maintaining a temperature at or near a melting point of the elastomer and a Curie temperature of the ceramic particulates. Because a material's dielectric constant is related to the material's net remnant ferroelectric polarization, which may be increased by poling near the material's Curie temperature, applying the electric field to the elastomer doped with the dielectric ceramic particulates increases the dielectric constant of the dielectric ceramic particulates. This maintains the high elasticity of the elastomer while increasing the elastomer's dielectric constant of the material by increasing the value of the dielectric constant of the dielectric ceramic particulates included in the elastomer.
