Electrospun fibers produced in dimethyl sulfoxide (DMSO) at a flow rate of 0.6 ml/h and the indicated concentrations of PES (panels (a) – (c)) with the addition of OTAB in (d). The fibers were analyzed by scanning electron microscopy and representative images are shown here. Scale bars represent 10 μm and 1 μm in each panel and inset, respectively.
