Effect of humidity on the surface morphology of a charged jet

In this work, we theoretically studied the effect of humidity on the charged jet in the electrospinning process. The obtained theoretical results offer in-depth physical understanding. The surface morphology of charged jet (such as the sizes of the microspheres and pores) are tunable by adjusting humidity. With increase in humidity, the surface features, or pores, of the jet become evident, and the sizes of microspheres are increased. © 2013 by Begell House, Inc.
