Abstract

In this study, the fabrication of polyvinylidene fluoride (PVDF) composite films enhances the fraction of β-phase. A simple and effective method is used to obtain crystallization of β-phase in PVDF directly from the melt. PVDF was used to dissolve with DMF, adding ionic liquid (IL) and casting at a specific temperature and time. IL can ultimately stimulate the PVDF crystallization during melting in the piezoelectric β-phase. PVDF composite films were immersed in hot water to remove IL. It found that piezoelectric properties were significantly increased while increasing the temperature of hot water. XRD investigates the characteristics of PVDF film composites. The PVDF composite's surface morphology and structure were examined using AFM and SEM. The output voltage response of the PVDF thin film sensor was measured for indicator performance.
