Using A Range of PVB Spinning Solution to Acquire Diverse Morphology for Electrospun Nanofibres

Popis výsledku v původním jazyce

Morphological changes in Polyvinyl Butyral (PVB) electrospun nanofibres can be acquired by preparation of PVB spinning solution in different solvents. Accordingly, three solvents, including ethyl alcohol, n-butanol and isopropanol, with diverse physicalproperties (e.g. boiling point, density, dipole moment and dielectric constant) were used to prepare PolyVinyl Butyral (PVB) spinning solution. The PVB polymer was used in two ranges of molecular weight. Scanning Electron Microscopy (SEM) was employed todetermine the morphological aspects. Results demonstrated a very high increase in the nanofibre diameter, with decreasing dipole moment and increasing boiling point and density of solvents. The smallest nanofibre diameter and bead structure was revealedfor the PVB solution prepared by n-butanol. With regard to morphological aspects, isopropnol was selected as the most suitable solvent for a range of PVB molecular weights
