Questions and Answers

What is the diameter range of fibers produced by electrospinning?

  • Some hundred nanometers (correct)
  • Several millimeters
  • Several centimeters
  • Several micrometers

    • What is the key advantage of electrospinning in producing fibers from large and complex molecules?

  • Requires minimal voltage for operation
  • Can produce fibers in macroscopic sizes
  • Produces fibers with uniform diameter
  • Does not require coagulation chemistry or high temperatures (correct)

    • What happens when a sufficiently high voltage is applied to a liquid droplet in electrospinning?

  • The droplet becomes charged and stretched, leading to eruption of a liquid stream (correct)
  • The droplet solidifies instantly
  • The droplet forms a perfect sphere
  • The droplet evaporates rapidly
