Effects of electrospinning parameters on the morphology of electrospun fibers.

Parameter	Effect of parameter on fiber morphology
Viscosity/concentration	Fiber diameters increased with increasing concentration/viscosity.
Applied voltage	The relationship between voltage and fiber diameter was difficult to ascertain.
Distance between nozzle and collector	To acquire dry fibers, a minimum distance was needed. Also, beading was seen at either too close or too far distances.
Flow rate	Fibers with smaller diameters were produced at lower flow rates, and excessive flow rates resulted in fibers that were not dry when they arrived at the collector.
Solution conductivity	In general, higher conductivities resulted in smaller fibers, but increasing conductivity facilitated in the creation of bead-free fibers that were consistent.
Ambient parameters	As the temperature rose, the viscosity of the solution decreased, resulting in smaller fibers. Increasing humidity caused the fibers to develop circular pores.
Surface tension	As the surface tension coefficient of the solutions increased, the quantity of beads increased.
