They were calledas “by products” that often can be seen in electrospinning. It was established that the cause of the beaded fibers is related to the instability of the jet of sample solution, net charge density carried by the electrospinning, the solution
viscosity and surface tension of the solution [16]. Continuous and smooth fibers could be obtained from PVC/LENR
solution when the other processing parameters were maintained (FIGURE 2 (b)).
