Piezoelectricity in Gamma-Form Nylon 11.

Abstract

X-ray studies of unpoled and poled gamma-form Nylon 11 films indicate that the polarization mechanism is not due to a field induced crystal transformation from the gamma to the alpha form, suggesting the existence of a polar gamma form. The temperature dependence of d31 shows no decrease in polarization at the alpha-gamma transition temperature (about 95 C) indicating that the hydrogen bonds in the poled film are not able to randomize. These results suggest the possibility that our understanding of the gamma form structure of Nylon 11 is incomplete. (Author)
