Abstract

Effect of annealing time on the microstructure and electromechanical properties PVDF TrFE CTFE terpolymer with 7.8 mol % CTFE was investigated to better understand structure-property relationships in these polymers. DSC results show that the 9 hr-annealing time gives the maximum enthalpy of melting which suggests the crystallinity of the polymer is increased. WAXS results show that annealing increases the proportion of the ã-phase with the ratio of the intensity of ã -phase to α-phase increases with more annealing time. Dielectric spectroscopic study of 9hr-annealed film also suggests that the film shows complete relaxor ferroelectric behavior with a maximum electrostrictive strain up to 4.4% compared to 4.1% for the 2.5 hr-annealed film. Finally, annealing time higher than 9 hrs result in a decrease in the electrostrictive strain.
