Coaxial electrospinning is a commonly used technique in pharmaceutical sciences that allows producing polymeric nano- or microfibers with core-shell structure. In addition to process parameters such as voltage and flow rate of the polymer solutions, the properties of such fibers are influenced by solu...
The diameter of the fibers was 2.0#177;0.25 #181;m when the DMAc-to-polymer-solution flow rate ratio was set as 0.1. The process technology reported here opens a new window to tune the polymer fibers obtained by the electrospinning, and is useful for improving productivity of the ...
FIRST STEPS OF CO-ELECTROSPINNING Coaxial electrospinning (co-electrospinning) was introduced first in Reference [1] . It bifurcated from electrospinning, a widely popular process of makingmonolithic polymer nanofibers coveredinseveral recent reviews. ...
So far, many researchers have demonstrated CE-Jet printing process such as Sun et al. generated special compositions known as core–shell polymer nanofibers by co-electrospinning method using PEO polymer material as internal fluid and PSU as external fluid18. Lee et al. described a multidrug ...
Coaxial electrospinning is a modification of the conventional electrospinning process (Díaz et al., 2008) involving the arrangement of multiple solution feed systems to simultaneously electrospin two or more polymer solutions from coaxial capillaries. From: Electrospun Nanofibers, 2017 ...
This method uses a coaxial convex needle and a two dimensional moving collector to deposit core-shell fibers by near-field localization and mechanical drawing force. A series of experiments were performed to determine optimum process parameters and results showed that with the substrate moving speed ...

In this study, the microencapsulation of rose hip seed oil (REO) in to a zein prolamine (ZP) fiber matrix via the coaxial electrospinning technique is studied. The morphological features of core-sheath REO encapsulated ZP fibers were modulated through process parameters (e.g. active and polymer...
Recently, Kim and team [55] proved that the printed coaxial microporous superfine fiber of the polycaprolactone (PCL)/collagen scaffold had better mechanical properties than the fibers prepared by a standard electrospinning process (greater than three times). An additional coating of type I collagen ...
In this study, the setup of the coaxial electrospinning process was designed similar to the one described in literature [40]. The outer tube had a diameter of 0.9 mm, whereas the inner tube had a diameter of 0.6 mm. The setup was designed to prevent the fluids from mixing before exiting...
