摘要

A double-switching-voltage phenomenon was found in traditional electrospinning with an auxiliary needle electrode where multiple jets (>= 2) only appeared between two threshold voltages. The effects of the double-switching voltage and other electrospinning parameters on the jet number were investigated. The number of jets increased as the increase of voltage, while the distances between the jets were found to be decreased with the increase of jet number. A possible interpretation of double-switching voltage formation was provided according to the theoretical analysis and finite element analysis of the electric field. Our results could provide the underlying insights needed to guide the design of electrospinning with enhanced throughput.
