The electrospinnability of visco-elastic sugar solutions
Appl. Rheol. 27:3 (2017) 35703 (10 pages)

It has been proposed that hydrogen bonding plays a role in promoting the electrospinnability of some materials. In this work,
the significance of non-covalent interactions in the electrospinnability of aqueous sugar solutions (i.e. mono- and disaccharide)
was investigated as a function of carbohydrate concentration. The electrospinnability of concentrated aqueous solutions of
glucose, fructose, and sucrose was studied by physicochemical and rheological characterization methods, and by subsequently
examining the resulting morphology via scanning electron microscopy. The results on the electrospinning of concentrated
saccharide solutions indicated the significance of non-covalent interactions on the electrospinning of these systems. Electrospinnability
models based on critical concentration and visco-elasto capillary theories were compared with the experimental
results. It is shown that visco-elasto capillary theory has the closest correlation with the experimental data. The electrospinnability
of highly concentrated saccharide solutions appears to be directly related to the density and intermolecular bonding
capacity of the solution.
