Abstract
Graphene nanoribbons (GNR) have shown great promise for applications in electronics, sensors, energy-conversion/storage devices, conductive composite materials, and biological fields. Commercialized GNR are mostly produced by unzipping high-quality carbon nanotubes (CNT), predominantly Mitsui CNT. Since the remaining stock of Mitsui CNT is running out, there is an urgent need for a reliable, cost-effective substitute. We studied three different brands of CNT as potential CNT sources in place of Mitsui CNT for making GNR. The NTL CNT and the Saratoga CNT were demonstrated to be well unzipped under both oxidative and reductive conditions based on scanning electron microscopy analysis. Raman and X-ray photoelectron spectroscopy were used to verify the efficacy of the unzipping reactions. The resulting GNR showed improved dispersibility in multiple solvents and similar electrical conductivity compared to the original CNT. The NTL CNT and the Saratoga CNT are expected to become a good substitute for Mitsui CNT in the large-scale production of GNR.
