Centrifugal multispinning, a new nanofibre production technique developed at the Korea Advanced Institute of Science and Technology (KAIST), is claimed to achieve up to 300 times the output of conventional electrospinning.
Electrospinning is the common process used to prepare fine and uniform polymer nanofibres, but has several drawbacks, such as the requirement of a high-voltage electric field and electrically conductive target.
Centrifugal spinning utilises centrifugal force instead of high voltage to produce polymer nanofibres and has been proposed as a safer and more cost-effective alternative to electrospinning. Achieving scale is another advantage since the technology only requires a rotating spinneret and a collector.
