Piezoelectric resonance spectroscopy was used to evaluate the face shear piezoelectricity and its relaxation for structurally controlled poly-L-lactic acid (PLLA) films. We prepared samples by uniaxial drawing at 80 degrees C for a ratio of 2-6 and annealed at temperatures above glass transition (Tg...
