It was confirmed by scanning electron microscopy that OS was homogeneously distributed in the PVDF matrix. The results of differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), and wide angle X-ray diffraction indicated that the incorporation of OS along with stretching treatment could effectively transform PVDF crystallization from the stable α phase to the most useful electroactive β phase. The interfacial interaction between PVDF and OS was analyzed by X-ray photoelectron spectroscopy and zeta potential. The dielectric properties, AC conductivities, mechanical properties, Rockwell hardness, and thermal conductivity of resultant OS/PVDF composites have been measured. More importantly, the piezoelectric coefficient d33and pyroelectric coefficient p of stretched OS/PVDF composites were enhanced significantly in comparison with the pure PVDF, making them promising materials for self-powered electronic systems, thermal detectors, sensors, and actuators.
