"Many people are trying to put as much graphene as possible into fibers," Dzenis said, adding that it is difficult to do. "But we did the unconventional thing: We used very small quantities followed by carbonization."
The resulting carbon nanofiber structure has an orientation similar to fibers with demonstrated enhanced strength and other properties, Dzenis said. He and his colleagues are now testing their graphene-based nanofibers for these enhanced properties as well as improving the technique.
The method is promising, he said. It could lower the cost of making composites significantly because it requires only small quantities of expensive nanoparticles and uses an inexpensive nanofiber manufacturing process, which was developed at UNL.
"All of this has potential for high-performance but, at the same time, low-cost carbon nanofibers," Dzenis said.
