Abstract

PVDF is used in various fields owing to its excellent mechanical and hydrophobic properties and its chemical resistance to corrosive chemicals such as acids, bases, and halides. A PVDF with a β-type crystal structure can exhibit both piezoelectric and ferroelectric characteristics. Thus, it can be used in a variety of electrical and electronic devices. In this study, we employed electrospinning using PVDF and metal oxides to manufacture β-type PVDF nanofibers. We also analyzed the crystalline structure of PVDF nanofibers with metal oxides. During the electrospinning, the crystalline structure of PVDF partially transformed from type α to type β. We confirmed that the transition value of PVDF crystalline structure from type α to type β scaled with the amount of BaO3Ti during the manufacture of PVDF nanofibers with BaO3Ti.
