[SEBB4113] - Electrospinning

What is the primary force used in the electrospinning technique?

• Gravitational force

• Centrifugal force

• Magnetic force

• Electric force

How does the distance between the needle and collector affect fiber diameter in electrospinning?

• Shorter distance produces thinner fibers.

• Longer distance produces thinner fibers.

• Distance has no effect on fiber diameter.

• Distance affects only the length of fibers, not the diameter.

What role does the Taylor cone play in the electrospinning process?

• It controls the voltage applied to the liquid droplet.

• It is the point where the liquid erupts into a stream from the surface.

• It ensures the fibers are uniformly thick.

• It heats the solution to the required temperature.

Which of the following parameters affects the viscosity of the electrospinning solution?

• Needle diameter

• Flow rate

• Molecular weight of the polymer

• Distance between needle and collector

What is the role of the power supply in the electrospinning process?

•  To heat the solution

• To provide high voltage

• To pump the solution

• To collect the fibers
