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