Measurement of Adhesion of In Situ Electrospun Nanofibers on Different Substrates by a Direct Pulling Method

Figure 3

SEM images of electrospun PVP fibers onto different substrates: (a) aluminium foil, (b) wood pulp paper, and (c) silicon paper at different electrospinning voltages of 11 kV (a1, b1, c1), 12 kV (a2, b2, c2), and 13 kV (a3, b3, c3). The inset images showed the average diameters of the as-spun fibers and their distributions.
