We report on the development of high-conductivity carbon nanotube (CNT) tapes with high stability at elevated temperatures (220 C) by a two-step FeCl₃-doping process at ambient pressure. Raman spectroscopy, electron microcopy, and thermogravimetric analysis reveal that this robust behavior is ascribed to the retentiveness of the dopants in the CNTs. These results advance the development of CNT tapes for practical cable applications under harsh conditions.
