[ link to eurekalert.org (secure)] The Lyding Group recently developed a technique that can be used to build carbon-nanotube-based fibers by creating chemical crosslinks. The technique improves the electrical and mechanical properties of these materials.
The paper, "Enhanced Electrical and Mechanical Properties of Chemically Cross-Linked Carbon-Nanotube-Based Fibers and Their Application in High-Performance Supercapacitors," was published in ACS Nano.
"Carbon nanotubes are strong and are very good at conducting heat and electricity," said Gang Wang, a postdoctoral research associate in the Lyding lab, which is at the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign. "Therefore, these materials have wide applications and can be used as strong fibers, batteries, and transistors."
There are many ways to build materials that have carbon-nanotube-based fibers. "Airplane wings can be made, for example, by embedding these fibers in a matrix using epoxy," said Joseph Lyding, the Robert C. MacClinchie Distinguished Professor of Electrical and Computer Engineering and a Beckman faculty member. "The epoxy acts as a binder and holds the matrix together."
