ABSTRACT:
A method of enhancing the piezoelectric properties of a polymeric material exhibiting such properties includes the step of exposing the material to a quantity of .gamma. radiation lying within the range of from 1 Mrad to 200 Mrads. The material is subsequently poled. Best results are obtained when the material is exposed to between 1 Mrad and 100 Mrads of radiation. The material treated may be polyvinylidene fluoride.
