Description	Journal: Materials Research Express Ferroelectric nanocomposite thin ﬁlms of Polyvinylidene Fluoride (PVDF) having 0 to 15wt% of Sodium Niobate (NaNbO3) nanorods, were prepared by solution casting method. Sodium Niobate nanorods were prepared by hydrothermal method. In the present work, it has been shown that the polar crystalline β-phase of PVDF, which is responsible for the piezoelectric property, enhances piezo properties from 52 to 75 % by adding appropriate quantity of NaNbO3 nanorods into the PVDF matrix without any additional mechanical and electrical treatment. The structural properties of nanocomposite ﬁlms are analyzed by X-ray diffractometer (XRD) measurements and polar crystalline β-phase has been analyzed by Fourier transform infrared spectroscopy (FTIR). The composite films synthesized from 15wt% loaded NaNbO3 in PVDF showed remnant polarization (Pr) is 0.01689μC/cm2 at an electric field of 150kV cm-1, generates maximum output voltage of 3.34V and short circuit current 0.01689 μC/cm2 by repetitive finger imparting pressure. The power so generated is sufficient to drive micro watt power consuming device. It has been shown that NaNbO3 nanorods not only facilitate the alignments of dipoles in PVDF but also increase the piezoelectric properties of the nanocomposite due to inherent piezoelectric property of NaNbO3 nanorods.
