Tuning Ferroelectricity in PVDF-TrFE through Thermal Treatment-Dependent Crystal Orientation.

ABSTRACT: The ferroelectric properties of poly-(vinylidene fluoride-co-trifluoroethylene) (PVDF-TrFE) films are critically dependent on its molecular orientation, due to the dipole-electric field match problem. This study systematically investigates the impact of the recrystallization temperature and cooling rate on crystal orientation and resultant ferroelectric performance during melt recrystallization of PVDF-TrFE thin films on mica substrates. The collective analysis of two-dimensional (2D) grazing incidence wide-angle X-ray diffraction (2D-GIWAXD), atomic force microscope (AFM), Fourier transform infrared-grazing incidence reflection absorption spectroscopy (FTIR-GIRAS), and polarization-electric field (P-E) hysteresis measurement data reveals that recrystallization at lower temperatures
