The PVB polymer was used in two ranges of molecular weight. Scanning Electron Microscopy (SEM) was employed to determine 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 revealed for 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 UR - https://ijcce.ac.ir/article_5920.html L1 - https://ijcce.ac.ir/article_5920_6d195d1448662ef088752ffc546d7493.pdf ER -
