ABSTRACT:
A piezoelectric polymer material comprising a cured product of a composition comprised of an epoxy resin having at least two epoxy groups in the molecules, a compound having a molecular weight not less than 1200 and containing defined numbers of amino groups, benzene rings, carbonyl groups and methylene groups, and a crosslinking agent. The cured product has dipolarly oriented micro crystals therein. A method for making such a piezoelectric polymer material is also described, in which the resin composition is thermally cured and contacted with an electric field at a high temperature to cause dipolar orientation in the product. The dipoles are frozen by cooling the product while applying the electric field.
