15/12/ · Later, PVP and DMF were used to produce AuNSs with tunable morphology, controlling the number of tips and their length For this, they varied the concentration of NaOH to control the pH of the reaction, which directly affects the final morphologies (see Fig 5) AuNRs have been produced by using a reduction process with hydroquinone and different phenols. The optimal electrospinning of all layers (PVC, PCL, and PVP) on paper towel (sacrificial substrate) was achieved by systematic optimization of key synthesis parameter matrix over an electrode working distance of 10 to 15 cm, an electric potential of 5 to 30 kV, a solution concentration of 2 to 30 w/w, a DTAB concentration of 0 to 2 mg ml −1, and a polymer solution feed rate of 05 to.
