Influence of Electric Field Interference on Three Nozzles Electrospinning

Abstract

The low production rate of electrospinning process may limit the industrial use of single needle system. To meet high yield requirement and uniform fibers, a bottom-up multiple jets electrospinning nozzle was designed. The influence of electric field interference on jet path, membrane shape and fiber morphology was investigated. Experiment finds that electrical field strength in the closer part of two nozzles is weakened due to electric field interference when the distance between two nozzles is close. Electric field, jet path, fiber web shape and fiber morphology of three nozzles electrospinning with linear arrangement, equilateral triangle arrangement and isosceles right triangle arrangement were also compared. Results show that electric field and spun fibers of three nozzles electrospinning with equilateral triangle arrangement is the most uniform.

Electrospun Nanofibers of Immiscible Blends Containing a Fluorescence Dye: Direct Investigation of Polymer Domains

“…The limitation of electrospinning for industrial uses is the low production due to the single needle technique. , Therefore, as the system studied is composed of solvents with high vapor pressure, the high evaporation rates of solvents can favor higher flow, which increases production of the nanofibers. Concomitantly with the increase in the flow, the applied voltages should be increased due to the more solution required for electrospinning process.…”

A new circular spinneret system for electrospinning numerical approach and electric field optimization

“…A double-row spinneret system was illustrated in fig.1. The double-row structure is conventionally used in the multi-needle electrospinning [22,25,27]. Figure 2 showed the distribution of electric field intensity in the surface of needle tips, the electric field intensity of the needle tips was calculated and drawn in fig.…”

“…The electric field distribution of electrostatic spinning spinneret influences the formation and movement of jets [23]. During the spinning process, the electric field distribution will cause an obvious phenomenon which is the end effect, and it is difficult to control the electric field [22,[24][25][26]. In this paper, the finite element method is used to simulate the electric field of the electrospinning spinneret.…”
