“…PEO could be dissolved in various kinds of solvents, such as water, alcohol, etc. [24], and had been widely used to carry out many kinds of experiment in the field of electrospinning [17][18][19][23][24]. The PEO solution properties could be adjusted easily by changing the solution concentration, which contributed significantly to the controlling technology research of mechanical and electrical spinning process.…”

In this paper, mechanical stretching force is introduced into the Electrohydrodynamic Direct-Write (EDW) process. The effects of mechanical stretching on the rheology and deposition behaviors of EDW jet were investigated. The stretching affects that stemmed from the EDW motion platform provided an extra force on the charged jet. The larger stretching force applied on the jet played a good role to overcome bending instability, and stretch the jet into finer ones. Since the short distance between spinneret and collector, the mechanical stretching force acted more important role on the jet formation process. Thanks to the stretching effect, the whipping of charged jet can be avoided and micro/nano thin film without curve structure can be direct-written on the collector. With increasing collector motion velocity, the line width and thickness of micro/nano thin film will be decreased. During the EDW process, the mechanical stretching force had provided an excellent aspect to control the morphology and deposition pattern of EDWed micro/nano thin film.

“…The control parameters of proportional integral derivative (PID) have been adjusted and optimized to increase the positioning accuracy. Automatic programming software has been built up [7], by which the AutoCAD drawings can be translated into command language code. The program code realizes the communication between drives and motors and drives the 2D motor to move at the pre-designed track.…”

Electrohydrodynamic Direct Writing (EDW) based on Near-Field Electrospinning (NFES) is a novel method to fabricate aligned micro/nano structure. In this article, linear motors and PIV&F servo control algorithm are introduced to set up an EDW experiment platform, by which patterned micro/nano structure can be direct-written. The motion track and position of collector is adjusted accurately by the platform, thus the deposition position and pattern of direct-written micro/nano structure can be controlled according to the pre-designed pattern. When motion velocity of collector higher than the ejection jet, micro/nano structure in straight line can be gained; but twisted structure can be direct-written under lower motion velocity of collector. The standstill of collector is introduced to overcome the pattern distortion that stems from the sharp change of collector motion track and the inertia of following jet. With the help of motion standstill, the patterned micro/nano structure without distortion can be direct-written, and more jet would be deposited at the corner of the pattern leaded to coiled structure. The EHD platform builds up the based for the industrial application of 1D micro/nano structure.
