United States Of America : Electrospinning Cellulose Waste Into Fiber |
|
2003-9-18
It may soon be possible to produce a low cost, high-value,
high-strength fiber from a biodegradable and renewable waste product for air filtration, water filtration and agricultural nanotechnology, report polymer scientists at Cornell University.
The achievement is the result of using the recently perfected technique of electrospinning to spin nanofibers from cellulose.
"Cellulose is the most abundant renewable resource polymer on earth. It forms the structure of all plants," says Margaret Frey, an assistant professor of textiles and apparel at Cornell. "Although researchers have predicted that fibers with strength approaching Kevlar could be made from this fiber, no one has yet achieved this. We have developed some new solvents for cellulose, which have allowed us to produce fibers using the technique known as electrospinning."
Frey is collaborating on the research with Yong Joo, an assistant
professor, and Choo-won Kim, a graduate student, both in chemical engineering at Cornell. Frey reports on the development Sept. 9 at the annual meeting of the American Chemical Society in New York City.
