Abstract
An electrospinning method includes providing a nozzle fluidically coupled to a source of polymer ink and providing a substrate adjacent to the nozzle. A first voltage is applied to the nozzle to initiate electrospinning of the polymer ink onto the substrate, wherein the first voltage is within the range of about 400V to about 1000V. The voltage is then reduced to a second, lower voltage wherein the voltage is within the range of about 600V to about 150V.
