Abstract

This study aims at investigating the piezoelectric behavior of nanofibers containing poly (vinylidene fluoride) (PVDF) with and without Fe₃O₄ nanoparticles at different concentrations. The nanofibers were formed using magnetic field assisted electrospinning. All Polymeric solutions contain PVDF, DMF and acetone with a concentration of 18 wt% (DMF to Acetone ratio of 3 to 1). Iron Oxide Nanopowder (Fe₃O₄, particle diameter of 20 nm to 30 nm) to PVDF ratios are: 1:5, 1:10 and 1:15. All nanofibers with nanoparticles in this study resulted with blisters related to Fe₃O₄ agglomerates distributed on the surface. Piezoelectric properties were observed in the all nanofibers after they are ejected and restructured by the electrospinning process, resulting the crystalline β phase.
