New process makes nanofibers in complex shapes and unlimited lengths
Date:1/30/2008

Yu and his students wound a coil of microfiber. The microfiber was approximately 850 nanometers in diameter and 40 centimeters long.

To further demonstrate the versatility of the drawing process, for which the U. of I. has applied for a patent, the researchers drew nanofibers out of sugar, out of potassium hydroxide (a major industrial chemical) and out of densely packed quantum dots. While the nanofibers are currently fabricated from water-based inks, the process is readily extendable to inks made with volatile organic solvents, Yu said.

Our procedure offers an economically viable alternative for the direct-write manufacture of nanofibers made from many materials, Yu said. In addition, the process can be used to integrate nanoscale and microscale components.
