POLYMER COMPOSITE PIEZOELECTRIC BODY AND METHOD FOR PRODUCING SAME

摘要

The purpose of the present invention is to provide: a method for producing a polymer composite piezoelectric body with high production yield, said polymer composite piezoelectric body being free from dielectric breakdown or separation even if the polymer composite piezoelectric body is formed to have a large area; and a polymer composite piezoelectric body. This polymer composite piezoelectric body is obtained by subjecting a composite body, in which piezoelectric particles are uniformly dispersed and mixed in a polymer matrix that is formed from a cyanoethylated polyvinyl alcohol, to a polarization treatment.
