Cover Story: Electrical and applied voltage annealing has been shown to increase the electrical conductivity of carbon nanotube (CNT) fibers to make them better electrical conductors. A study of thermal annealing in a vacuum up to 800 °C was performed on smaller fiber sections along with a separate analysis of voltage annealing up to 7 V; both exhibited an optimal condition in the process as determined by a combination of two-point probe measurement with a nanoprobe, resonant Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). Scaled-up tests were then performed to translate these results into bulk samples inside a tube furnace, with similar results that indicate the potential for an optimized method of achieving a better conductor samples made from CNT fibers.
