Abstract

Currently, the most important PVDF polymorph is the β-phase, which has a net crystalline dipole moment oriented precisely normal to the molecular chain. This dipole moment is responsible for the enhancement in piezoelectric and ferroelectric activities. Nanofibers prepared by electrospinning are a desirable material for air filtration applications owing to their high porosity, micro-nano channel interconnects, and high surface-area-to-volume ratio. Electrospinning nanofibers have a high surface-area-to-volume ratio, an adjustable porous structure, and a facile preparation process, making them a suitable candidate for filtration materials. Previous studies have reported structural variation in electrospun PVDF nanofibers in the presence of BaO3Ti via the formation of β-type increment crystallites. In this study, two nanofiber samples prepared by the electrospinning of PVDF and PVDF/BaO3Ti solutions were used to investigate the air filter efficiency and pressure drop and understand the effect of the crystal structure change of PVDF nanofibers on the filtration performance. For nanofibers prepared by electrospinning a solution containing a mixture of BaO3Ti and PVDF, the β-type crystal structure transition and dielectric constant improved. The results indicated that the realization of high-performance filter materials with a low pressure drop at the same high filter efficiency is possible.
