摘要
Poly (vinylidene fluoride) (PVDF) electrospun mats were prepared by electrospinning.The fiber mats were collected by a high-speed rotating drum to obtain a certain degree of orientation.Characterized by scanning electron microscopy, IR spectroscopy, wide angle X-ray diffraction characteristics, the PVDF fibers showed oriented β crystal.Inorganic additives and heat treatment can improve crystalline form of PVDF and its piezoelectric performance.The piezoelectric properties were also studied and results showed that the piezoelectric properties were influenced by the frequency of force and the thickness of mats.
