DIELECTRIC MATERIAL FOR TRANSDUCER, METHOD FOR PRODUCING SAME, AND TRANSDUCER USING SAME

摘要

A dielectric material for a transducer (1) is manufactured from a composition that includes metal oxide particles having hydroxy groups, a rubber polymer having a functional group capable of reacting with an epoxy group, a bisphenol type epoxy resin, both ends of which have an epoxy group, and a cross-linking agent. In the dielectric material for a transducer (1), the metal oxide particles (12) are bound to the rubber polymer (10) via the bisphenol type epoxy resin (11). A transducer (2) includes a dielectric layer (20) made of the dielectric material for a transducer (1) and a plurality of electrodes (21a, 21b) arranged with the dielectric layer (20) interposed therebetween.
