The Analysis of Forming PVB-SiO2 Nanocomposite Fibers by the Electrospinning Process
Vera Obradović Aleksandar Kojović Dušica B. Stojanović Nebojša Nikolić Irena Živković Petar Uskoković Radoslav Aleksi The poly (vinyl butyral)-silica (PVB-SiO2) nanofibers were obtained by the electrospinning process. The experiments were carried out with PVB solution in concentration of 10 wt.% where ethanol was used as the solvent. The silica nanoparticles were added in the solution in different contents of 1, 3 and 5 wt.% SiO2 and nanoparticles were modified with γ-aminopropyltriethoxysilane (AMEO silane). The impacts of the parameters of the electrospinning process and the silica nanoparticles on the produced PVB-SiO2 nanocomposite fibers were tested. The structures of the PVB-SiO2 nanocomposite fibers were investigated using optical microscopy and scanning electron microscopy (SEM). The morphology and distribution of the resulting nanofibers were analyzed using the software Image-Pro Plus. Key words: nanofibers, nanocomposite fibers, nanoparticles, aminopropyltriethoxysilane (AMEO silane), PVB-SiO2, electrospinning method, experimental results.
