Characterization Of Pvdf Nanofibers Created By The Electrospinning Method

Abstract

The work investigates structure and properties of composite fibers created by the electrospinning method for piezoapplications. Polyvinylidene fluoride (PVDF) was used as a precursor. As an electrospining parameter, the collector speed of 300 and 2000 rpm was selected, which significantly affects the properties of nanofibers. The structure of fibers was investigated by scanning electron microscopy (SEM) using focused ion beam (FIB). Morphology and piezoelectric domains was observed using piezoresponse force microscopy (PFM). Phase composition was identified using Raman spectroscopy and by Fourier-transform infrared spectroscopy (FTIR). Found results are essential for the design and construction of piezoelectric based structures.
