The Taylor cone formation from the free polymeric layer and the start of the electrospinning process: Taylor cone formation (a–c) and relaxation of polymeric droplet (d–i). Start of the spinning process (i). Reaction of electric and capillary forces can be observed. The angle of the Taylor cone (c). Needle electrospinning of 12 wt.% PVA, = 30 kV. Electrospinning was carried out at laboratory conditions.
