Soft, Lightweight, Multi-Functional Conductors from Fullerene Carbon Nanotubes
Abstract
In an earlier AFOSR grant, we demonstrated that chlorosulfonic acid (CSA) can dissolve long carbon nanotubes (CNTs) and can be used as solvent for spinning CNT fibers and produce CNT films and coatings. However, since CNT length plays a crucial role in the electrical and mechanical properties of CNT fibers and films, it is fundamental importance to effectively determine the bulk length of the CNT source materials used for the CNT fiber/film manufacturing. Therefore, methods are needed for measuring CNT length accurately and easily. Under Grant FA9550-15-1-0370 in year 1, we developed a method to measure the CNT bulk average length from extensional viscosity measurements of semidilute CNT-CSA solutions.
