Major gains with centrifugal multispinning

Major gains with centrifugal multispinning
Rotating spinneret is sectioned into three sub-disks.
21st May 2021
A new nanofibre production technique developed at the Korea Advanced Institute of Science and Technology (KAIST) is said to achieve up to 300 times the output of the conventional electrospinning process.
Electrospinning has been the common process used to prepare fine and uniform polymer nanofibres but has several drawbacks, such as the requirement of a high-voltage electrical field and an electrically conductive target.
Existing centrifugal spinning technology employs centrifugal force instead of high voltage to produce polymer nanofibres and is being 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. ....
