  • Abstract
    The charging capability and Young´s modulus of XPP films can be modified by a hot-stretching process. The results show that the onset of piezoelectricity occurs at an elongation ratio of 70% and enhances with the increase of this ratio. A quasistatic piezoelectric d33-coefficient of 308pC/N is achieved for samples with an elongation ratio of 200% and a Young´s modulus of 0.54MPa. An improved piezoelectric d33-coefficient is obtained for samples with a rough surface exposed to the corona during charging.
