This study explores the mutual correlation between structures of electrospun fibrous membranes prepared from polyvinyl butyral (PVB) and the wettability of the same. The final morphology of the fibres (wrinkled, smooth, ribbonlike and porous) was investigated by dissolving the PVB in various solvents and solvent mixtures. It was found that some concentrations of PVB in certain solvents and their mixtures exerted an influence on the diameter of the given fibre and water contact angle. The nanofibrous membranes were produced via electrospinning, and characterized by scanning electron microscopy (SEM) and measurement of contact angle. Discussion is included on comparison of the wettability of the PVB films and nanofibres.
