Effect of mechanical treatment and fabrication temperature on piezoelectric properties of PVDF film (original) (raw)

AIP Conference Proceedings, 2015

Abstract

ABSTRACT Piezoelectric properties are one of the electrical properties that will arise in case of mechanical disturbances. One of polymer that can produce the greatest piezoelectric properties is poly vinylidene fluoride (PVDF). Piezoelectric properties of PVDF can be improved by mechanical treatment on the varying film thickness and the temperature. PVDF film has produced by roll hot press tool. Furthermore, PVDF films were characterized by XRD, IR and I-V meter. We have been obtained an increase piezoelectric properties of PVDF films that characterized by increasing ȕ fraction. We get ȕ fraction was 63.63%, 66.35% and 71.60% for temperatures of 140, 150 and 160 C, respectively at film thickness of 13 μm. In addition, We have gained ȕ fraction for the thickness of 15, 13 and 8 μm are 64.60%, 66.35% and 69.00%, respectively at temperature of 140 C. This is due to the increasing temperature and decreasing film thickness then more dipoles are oriented in PVDF films. These results indicate that mechanical treatment caused difference film thickness and temperature of PVDF film has a strong influence on the piezoelectric properties.
