Electrohydrodynamic Printing via Spinneret with Conductive Probe
Stability jet ejection and precision deposition are the two keys for industrial application of electrohydrodynamic printing.In this paper,inserted conductive probe is utilized to gain stability jet,which would increase the electrical field strength,reduce the back flow,onset and sustaining voltage.Lower applied voltage would enhance the stability of electrospun jet,in which fine jet can be used to direct-write orderly Micro/Nano-structure.With the guidance and constrain of inserted probe,the oscillating angle range of electrohydrodynamic jet is decreased to 3°from 15°,and the width of printed structures is 21μm in average that is much narrower than that printed from spinneret without probe (74μm in average).Spinneret with tip provides a good way to improve the control level of electrohydrodynamic printing,which would accelerate the industrial application of electrohydrodynamic printed Micro/Nano structure.
