Chemical defects induced in P(VDF-TrFe) by electron irradiation

Abstract

Abstract The chemical defects produced by electron irradiation of P(VDF-TrFe) have been studied using XPS and UV spectroscopy. As a result of irradiation it was found that the fluorine content was decreased, mainly through HF desorption. Correlatively, double bonds and conjugated double bonds were produced. As a consequence, the concentration of dipole moments and the dipolar energy were reduced in consistency with the depression of the Curie temperature after irradiation.
