Experimental Investigation on the Multiple Jets from a Single Droplet by Electrospinning
In electrospinning, outlook of fibrous assembly changes not only with the variation of collecting setups, but with the electrospinning process. For example, formation of multiple jets on a single droplet at special electrospinning conditions can produce several regions of fibrous webs simultaneously, which is bound to bring a great increase of production of nanofibers. The initiation method of multiple jets during electrospinning was derived through an experimental investigation by means of a high-speed camera, which was used to obtain the information of the shape change of a droplet along with process conditions, such as solution concentration, voltage and flow rate. Results showed that multiple jets could be initiated in a controlled manner when droplets experienced several cycles of dripping at relatively high voltages and flow rates in a certain concentration range. An interesting phenomenon of the auto-initiation of double jets was further observed in our experiment.
