Piezoelectric polymer material and method

Abstract

The present invention provides a method of manufacturing the piezoelectric polymer material, the piezoelectric polymer material having a weight average molecular weight of 50,000 to 1,000,000 and having an optically active aliphatic polyester (A), and a carbodiimide selected from the group consisting of one kind or more functional groups of sub-group, an epoxy group and an isocyanate group consisting of a weight-average molecular weight of 200 to 60,000 stabilizer (B), the degree of crystallinity obtained by the DSC method is 20% to 80%, relative 100 parts by weight of the aliphatic polyester (A), containing the stabilizer (B) 0.01 parts by weight to 10 parts by weight.
