Abstract:
High performance piezoelectric polymers have been gained increasing attention from industry and academia particularly for applications in wearable electronic devises. In this study, we show that the piezoelectric response of poly (vinylidene fluoride) (PVDF) nanofibrous can be enhanced by zirconium-based metal-organic framework (MOF). Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy were utilized to investigate the effect of MOF particles on morphological and structural properties, especially the β crystalline phase content, of produced PVDF-MOF composite. The PVDF nanofibers with average size of about 60 to 80 nm were prepared by the electrospinning process. It shown that MOF particles slightly increase the size of the nanofibers but stabilize the β crystalline phase. The highest improvement in the piezoelectric response is attained at 5 wt.% of MOF. Moreover, the piezoelectric output of the PVDF-MOF nanofibrous composites increased by 50% as compared with pristine PVDF nanofibers.
