Solution electrospinning with a pulsed electric field

Abstract

Getting finer fibers is one important goal of electrospinning. In this article, we introduce orthogonal experimental research of solution electrospinning with a pulsed electric field. The influences of the voltage, flow rate, frequency, and duty cycle on the mean diameter and diameter distribution of electrospun fibers were investigated. The phenomenon of electrospinning in a pulsed electric field was compared to that of electrospinning in an ordinary electric field. We found that the order of the factors that affected the fiber diameter was Duty cycle > Flow rate > Voltage > Frequency and the order of factors that affected the fiber diameter distribution was Duty cycle > Flow rate > Frequency > Voltage. In addition, compared with the ordinary electric field, the pulsed electric field apparently contributed to reductions in the mean fiber diameter and diameter distribution. In this article, we provide important evidence for the reduction of the fiber diameter with the pulsed electric field. V C 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46130.

Desired properties and corresponding improvement measures of electrospun nanofibers for membrane distillation, reinforcement, and self‐healing applications

“…An increase in flow rate results in a larger fiber diameter, while a further increase has no noticeable effect. [ 81 ] For cyclodextrin polymer nanofibers, if the flow rate is increased from 0.1 to 2 mL hr −1 , the mean diameter increases considerably from 610 to 1860 nm. [ 82 ]…”
