The analysis of stability of the electrospinning process of forming PVB-SiO2 nanocomposite fibers

Abstract

The PVB-SiO2 composite nanofibers were obtained by the electrospinning process. The experiments were carried out with PVB solution in concentration of 10 wt% where as the solvent was used ethanol. The silica nanoparticles were added in the solution in different content of 1, 3 and 5 wt% SiO2, and they were both modified and unmodified with amino-silane. The impact of the parameters of the electrospinning process on the produced PVB-SiO2 nanocomposite fibers was tested. The structures of the PVB-SiO2 nanocomposite fibers were investigated using scanning electron microscopy (SEM) and characterized by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and thermogravimetric (TG) analysis. The morphology and distribution of the resulting nanofibers were analyzed using software Image - Pro Plus.
