collector was grounded and kapton u00ae polymer film was placed around the barrel of the collector to create an insulative surface an alligator clip was used to attach the high voltage power supply to the needle to distribute a positive voltage of 10 kv to the polymer solution pga was electrospun using a 10 ml syringe and a 22 gauge blunt end needle at a constant flow rate of 1 5 ml hr the rotating collector was positioned 10 17 cm from the tip of the needle and a positive voltage of 15 kv was applied to the polymer solution for each polymer an auxiliary electrode stainless steel needle was positioned at an angle 90 u00b0 directly above the top of the rotating collector using a plexi glass mounting bracket an alligator clip was used to attach the high voltage power supply to the auxiliary electrode to generate a negative voltage equal and opposite to the positive voltage fibers and mats were coated with 4 8 nm of au pd using a sputter coater images were obtained using a scanning electron microscope and a high resolution scanning electron microscope image processing and analysis of fiber diameter and degree of alignment were performed high speed videos were captured at 2000 frames sec and data was processed and post processed high speed video imaging was used to capture the fiber from jet initiation through collection on the rotating mandrel jet exit images illustrated the stability of the fiber as it overcame surface tension and was.
