New nanotech fiber: Robust handling, shocking performance
Date:1/10/2013

ts. But the process needed to be refined. The fibers weren't very strong or conductive, due partly to gaps and misalignment of the millions of nanotubes inside them.

"Achieving very high packing and alignment of the carbon nanotubes in the fibers is critical," said study co-author Yeshayahu Talmon, director of Technion's Russell Berrie Nanotechnology Institute, who began collaborating with Pasquali about five years ago.

The next big breakthrough came in 2009, when Talmon, Pasquali and colleagues discovered the first true solvent for nanotubes -- chlorosulfonic acid. For the first time, scientists had a way to create highly concentrated solutions of nanotubes, a development that led to improved alignment and packing.

"Until that time, no one thought that spinning out of chlorosulfonic acid was possible because it reacts with water," Pasquali said. "A graduate student in my lab, Natnael Bahabtu, found simple ways to show that CNT fibers could be spun from chlorosulfonic acid solutions. That was critical for this new process."

Pasquali said other labs had found that the strength and conductivity of spun fibers could also be improved if the starting material -- the clumps of raw nanotubes -- contained long nanotubes with few atomic defects. In 2010, Pasquali and Talmon began experimenting with nanotubes from different suppliers and working with AFRL scientists to measure the precise electrical and thermal properties of the improved fibers.

During the same period, Otto was evaluating methods that different research centers had proposed for making CNT fibers. He envisaged combining Pasquali's discoveries, Teijin Aramid's know-how and the use of long CNTs to further the development of high performance CNT fibers. In 2010, Teijin Aramid set up and funded a project with Rice, and the company's fiber-spinning experts have collaborated with Rice scientists throughout the project.
