Rotary or centrifugal jet spinning is a technique used to produce nanofibers. It involves the use of a high-speed rotating disc or drum to create a centrifugal force, which extrudes a polymer solution through a small nozzle to form continuous nanofibers.
Some advantages of rotary or centrifugal jet spinning include the ability to produce continuous nanofibers at high production rates, as well as the potential to produce a wide range of nanofiber diameters. It also allows for the production of nanofibers from a variety of polymers and the incorporation of functional materials.
Rotary or centrifugal jet spinning has a wide range of applications in various fields such as biomedicine, energy, and textiles. It can be used to produce nanofibers for tissue engineering, drug delivery, filtration, and reinforcement in composites, among others.
One limitation of rotary or centrifugal jet spinning is the inability to control the alignment of nanofibers, leading to a random orientation. It also requires a high-speed rotation, which can be challenging to maintain over long periods. Additionally, the process may result in some defects in the nanofibers.
Compared to other techniques such as electrospinning or melt spinning, rotary or centrifugal jet spinning offers higher production rates and the ability to produce a wider range of nanofiber diameters. However, it may not be suitable for producing highly aligned nanofibers or for certain types of polymers that are not compatible with the process.
